Difference Between LP And Propane: Is There Any?

Liquefied petroleum (LP) and propane can be confusing because it’s the same thing.  Even though LP is classified as propane, all propane is not LP. Meaning LP stands for one class of propane; it’s just that one is liquefied while the other is in vapor form. The form is what marks the difference between the two. 

In other words, it’s the same as the difference between ice and water. Apart from the form, its features, consideration, uses, and identification also brings some slight differences, as discussed below. 

Difference Between LP And Propane

What Makes LP And Propane Different?

We will look at the characteristics of LP compared to propane to understand their differences better. This is significant as the two substances are used for cooking and heating, with both having a dangerous factor that needs to be identified for safety reasons. 


Propane is a by-product produced during the refining process of natural oil and gas which comes out of wells. That means you cannot find propane naturally; instead, it’s liquified before being stored. Propane can only be stored in liquid form, and the process needs a minimum temperature of forty-four degrees under zero Fahrenheit to be completed. Typically, LP is an icy substance that can damage your skin seriously. Suppose the propane temperature is increased from forty-four degrees under zero; it transforms from liquid to vapor or gas, making the differences between them.


There are specialized containers designed for the purpose to transport and store LP. They are usually kept in large containers or resembling tubes. For home use, the cylinders are designed with handles to provide ease of transportation and storage. LP is a dangerous substance that can ignite the fire and cause an explosion if care not taken seriously. To avoid such, keep your cylinder in an upright position.


You cannot mix both substances in one appliance. When propane vapor is needed for gas stove operation, it will use it, and LP can never be its substitute. Like any device manufactured for LP, it cannot use propane vapor. Yes, both are propane though it’s indifferent and is not compatible in this own state.


Propane is colorless and doesn’t have an odor when it’s in vapor form. Its presences present danger because it has been subjected to ignition and explosion. As compared to air, propane is heavier. When exposed to an open area, that feature doesn’t cause any issues since the air will carry the vapor away. Likewise, when propane is exposed to a closed room, a house will settle down on the floor and remain still where possible; a spark could ignite it.

Is LP Gas And Propane The Same Thing?

When propane is put under pressure in a stored tank, it turns into liquid due to the pressurized state. But there is a catch here; all LP can be classified as propane, but not all propane is LP.  Meaning some LP is not propane but rather any other liquified gas that is not propane. However, when talking about the grill, then propane gas and LP refer to the same thing.

Generally, if you open a valve on a propane cylinder to use the grill, LP will be boiling back into propane gas, which is directed into your grill via the regulator or hose. When liquid propane turns into a gas due to boiling, its temperature drops to about -40°F. That explains why many propane cylinders feel cold when you touch and it also why condensation forms on them during a hot summer period.

Propane as an LPG is perfect for exterior storage and use. Its capacity to operate in low temperatures makes them the ideal LPG for various applications. When it comes to domestic use and industrial heating, cooling, and hot water, propane gas is the one used majorly as the source of fuel. It is also used in industries and agriculture. If the energies need to be stored for an extended period, propane is usually a better option than other gases like butane.

Can LP Gas Kill You?

It’s no doubt that LPG is a dangerous substance when precautions are not taken seriously and can lead to tire consequences like death. So, it’s true LP gas can kill you easily when there is a leak; the same way that it produces a lot of heat when you burn a small amount. It’s quite the same when there is a gas leak. It can pose a serious risk of fire or an explosion. Ignited gas spread faster and goes up into flames easily, leading to death. Suppose there is a gas leak in the house; any electric spark or fire source can ignite the gas, causing devastating results.

It’s paramount for you to learn its precautionary measures first before usage. It is important to know how to detect the gas leak and avoid any possible danger. Also, note this, a natural gas leak at certain levels can kill you through suffocation if it doesn’t ignite. It’s pretty the same way that carbon monoxide can kill you by preventing your body from absorbing oxygen. LP gas or natural poses the same risk in the air at high concentrations, causing the same effect.

Can A Carbon Monoxide Detector Detect Propane?

A carbon monoxide detector isn’t the best detector for propane cylinder leaks, which puts homeowners at higher risk. However, a CO detector does not protect people who use propane for heating and cooking. To determine if there is a propane leak taking place, you should be keen on a distinct odor similar to rotten eggs. A subtle sound of propane escaping the gas line can also help detect a leak. It is advisable to call a gas company or emergency service immediately in case of any leakage.

A carbon monoxide detector works by recognizing gas that you can’t see or smell. The device is susceptible, though you need to place it properly for it to function optimally. They are made to alert homeowners before the carbon monoxide reaches deadly levels, meaning they need to be lower or head levels. Avoid putting detectors near the ceiling attachments, such as a smoke alarm, since it won’t do enough to keep you safe. Rather look for a place in your house near your kitchen area away from the ceiling.

What Kind Of Detector Do You Need For Propane?

Safety is a priority concern when dealing with a gas leak of any sort. You can easily detect the propane gas leak without using any detectors by simply smelling. Propane gas has an odor that many homeowners can smell easily. Propane manufacturers normally add a stench similar to that of a rotten egg for easy detection through smell when there is a leak.  

Nonetheless, you can consider some simple ways, such as using a home detector solution and electronic gas leak detector to determine if there are propane leaks in the house. These are expounded below: 

1. Homemade Detector Solution: This is one way you can easily detect a gas leak. You need to mix a small amount of dishwashing soap with water in a bowl. Then brush the mixture on the suspected area or, better yet, fill a spray bottle with the mixture. Spray the suspected leak area with the mixture. When you see the bubbles forming, indeed, there is a leak, and you should immediately call a technician for repair.

2. Electric Gas Leak Detector:  This is also a special device designed to detect the air’s abnormal concentration of combustible gas. When it detects gas’s presence, it automatically triggers the alarm, thus informing you of any leak. Luckily, the detectors are available in most home improvement or hardware stores at $40 to $100.

Is Propane The Same As Butane?

Propane is not the same as butane. The former is a by-product of natural gas processing and oil refining. It’s liquefied through pressurization to form a flammable hydrocarbon gas. Propane is popularly used for heating and cooking in a wide range of residential and commercial use. In contrast, butane is combustible hydrogen gas from natural oil refining and gas processing. Unlike propane, butane is popularly used as a fuel, refrigerant, and propellant.

Though both have similar qualities, there are certain disparities among them. The differences could either be beneficial or limitation depending on their uses. 

The main difference is that the two gases have a distinct boiling point. Propane has a boiling temperature of -40°C; butane got a higher boiling point of -2°C. This means propane will continue to vaporize and turn to gas while in colder climates, which is good for the cold winters. If stored in a liquid in a cylinder, propane exerts greater pressure than butane while in the same environment, making it perfect for exterior storage and uses.


Both propane and butane are usually sourced from natural gas and oil, and they belong to the LPG family plus other gases. Thus, LP could be classified as propane even though all propane is not LP. Basically, propane and LPG are the same things.

Either of the two poses a great danger to us and our environment if we do not take the necessary precautions. Nowadays, there are different ways of detecting gas leaks using various detectors. ‘Prevention is better than cure,’ so take precautionary measures when using the gases to avoid unnecessary disaster.
