The megajoule (MJ) equals 1,000,000 joules and is used for large-scale energy measurements in engineering, transportation, and industrial processes.
One liter of petrol contains about 34 MJ of chemical energy. A bolt of lightning releases about 1-5 MJ. An adult's daily food intake is roughly 8-10 MJ. Electric vehicle batteries are typically rated at 40-100 MJ (11-28 kWh).
Interesting fact: The kinetic energy of a 1,000 kg car traveling at 100 km/h is about 0.385 MJ. TNT explosive releases about 4.6 MJ per kilogram when detonated.
The therm is a unit of natural gas energy equal to 100,000 BTU (105,480,400 joules). It is the standard billing unit for natural gas in the United States and United Kingdom. The name comes from the Greek thermos (heat).
Gas utilities bill residential and commercial customers in therms in the US and UK. A typical US household uses about 50–100 therms per month in winter. Natural gas furnaces and water heaters are rated in therms per hour.
Interesting fact: One therm of natural gas costs about $1.00–$2.00 in the US. Burning one therm releases about 5.3 kg of CO₂. The US consumes about 28 trillion therms of natural gas equivalent energy per year.
Converting megajoule to therm is common across energy, nutrition, engineering, and science. Different sectors use different energy units — joules in physics, kcal in nutrition, kWh in electricity, and BTU in HVAC — making accurate conversion essential for cross-disciplinary work and international comparisons.
Quick reference: 5 MJ = 0.0474 therm and 10 MJ = 0.0948 therm. Reverse: 1 therm = 105.5 MJ. Exact factor: 1 MJ = 0.00948 therm.
All conversions use IEEE 754 double-precision arithmetic, accurate to at least 8 significant figures.
