The foot-pound (ft·lb) is an Imperial unit of energy equal to the work done when a force of one pound-force moves an object one foot, equaling 1.35582 joules. It has been used in British and American engineering since the 18th century.
Foot-pounds are standard in US mechanical engineering for torque specifications, engine output (often ft·lb of torque), and ballistic energy measurements. Rifle bullet energies are commonly quoted in foot-pounds in American publications.
Interesting fact: A typical 9mm pistol bullet has about 350 ft·lb of muzzle energy. The torque specification for tightening a car wheel bolt is typically 80–100 ft·lb. One horsepower equals 550 ft·lb per second.
The megawatt-hour (MWh) equals 1,000 kWh or 3.6 × 10⁹ joules. It is the standard unit for utility-scale electricity generation, large industrial consumers, and grid-level energy storage.
Power plants, wind farms, and solar installations are rated and billed in MWh. A 2 MW wind turbine generates about 6 MWh per day on average. Large data centers consume thousands of MWh per month.
Interesting fact: The Hoover Dam generates about 4,000 MWh per hour. A single nuclear power plant produces about 8,000 MWh per hour. World electricity consumption is approximately 25,000 TWh (25 billion MWh) per year.
Converting foot-pound to megawatt-hour 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 ft·lb = 1.8831e-9 MWh and 10 ft·lb = 3.7662e-9 MWh. Reverse: 1 MWh = 2.655e+09 ft·lb. Exact factor: 1 ft·lb = 3.7662e-10 MWh.
All conversions use IEEE 754 double-precision arithmetic, accurate to at least 8 significant figures.
