1 LPG equals approximately 34.2 megajoules.
This is because liquefied petroleum gas (LPG) contains an energy content averaging around 25.7 megajoules per liter. Converting 1 liter of LPG to megajoules involves multiplying by this energy density, giving a precise measurement of its energy in the metric unit of megajoules.
Conversion Result and Explanation
Converting 1 lpg to megajoules yields about 34.2 MJ. The calculation uses the energy content per liter of LPG, which is roughly 25.7 MJ. Therefore, multiplying 1 liter by 25.7 MJ gives us the energy in megajoules, making it straightforward to understand LPG’s energy capacity.

Conversion Formula
The formula to convert liters of LPG to megajoules multiplies the volume in liters by the energy content per liter, which is approximately 25.7 MJ. This works because energy density represents the amount of energy stored in a given volume, allowing us to calculate the total energy.
For example, if you have 2 liters of LPG, the calculation would be 2 * 25.7 = 51.4 MJ, showing how the total energy scales directly with the volume of LPG.
Conversion Example
- Convert 0.5 liters of LPG:
- Multiply 0.5 by 25.7 MJ
- 0.5 * 25.7 = 12.85 MJ
- So, 0.5 liters has about 12.85 megajoules of energy.
- Convert 5 liters of LPG:
- 5 * 25.7 = 128.5 MJ
- This means 5 liters contain around 128.5 megajoules.
- Convert 1.25 liters of LPG:
- 1.25 * 25.7 = 32.125 MJ
- Therefore, 1.25 liters equate to approximately 32.125 megajoules.

Conversion Definitions
LPG, liquefied petroleum gas, is a mixture of hydrocarbon gases like propane and butane stored under pressure. It is used as fuel for heating, cooking, and vehicles, and has an energy density measured in units like megajoules per liter, reflecting its energy capacity.
Megajoules (MJ) are units of energy in the metric system, representing one million joules. Joules are fundamental units measuring work or energy transfer, used across physics, engineering, and energy industries to quantify energy amounts in various forms.
Conversion FAQs
How accurate is the 25.7 MJ per liter value for LPG?
This value is an average based on typical LPG compositions. Actual energy content can vary depending on the specific mixture and temperature, but 25.7 MJ per liter is a reliable standard for most calculations involving LPG energy conversions.
Can I convert LPG volume to energy in other units like calories?
Yes, but you need to know the conversion factors: 1 joule equals approximately 0.239 calories. To convert liters of LPG to calories, multiply the megajoules value by 1,000,000 (to get joules), then multiply by 0.239 to get calories, although this is less common in technical contexts.
Why does the energy content per liter vary in different sources?
The variation results from differences in LPG composition, temperature, and pressure conditions. Since LPG is a blend of hydrocarbons, the exact energy density can fluctuate, so standard values are used for general calculations.
How can I convert multiple liters of LPG to energy quickly?
Multiply the number of liters by 25.7 MJ. For example, 10 liters * 25.7 MJ = 257 MJ. This simple multiplication allows quick estimation without complex calculations, especially useful for budgeting or energy planning.
Is the conversion factor valid for all types of LPG?
The 25.7 MJ per liter applies mainly to typical commercial LPG mixtures. Variations in composition, purity, or additives may slightly alter the actual energy content, but for most practical purposes, this value is sufficiently accurate.
