British Thermal Unit (Btu), calorie, joule, kilojoule, electron volt, erg, foot lbf, foot poundal, kilocalorie, kilowatt hour, watt hour
 
1 J (Joule) = 0,1020 kpm = 2.778x10-7 kWh = 2.389x10-4 kcal = 0.7376 ft lbf = 1 (kg m2)/s2 = 1 watt second = 1 Nm = 1 ft lb = 9.478x10-4 Btu
1 kpm = 9.80665 J = 2.724x10-6 kWh = 2.342x10-3 kcal = 7.233 ft lbf = 9.295x10-3 Btu
1 kWh = 3.6x106 J = 3.671x105 kpm = 859.9 kcal = 2.656x106 ft lbf = 3.412x103 Btu
1 kJ = 1 kNm = 1kWs = 103 J = 0.947813 Btu = 737.6 ft lbf = 0.23884 kcal
1 Btu (British thermal unit) = 1,055.06 J = 107.6 kpm = 2.92875x10-4 kWh = 251.996 calorie = 0.252 kcal = 777.649 ft lbf = 1.0544x1010 erg = 0.293 watt hour = 0.999331 Btu (Int Steam Tab) = 0.998560 Btu (mean) = 25020.1 foot-poundal = 107.514 kg force meter = 1.0751x107 gram-force cm = 0.000393 hp-hour = 10.456 liter atm = 1054.35 wattsecond
1 cal = 4.186 J
1 kcal = 4186,8 J = 426,9 kp m = 1.163x10-3 kWh = 3.088 ft lbf = 3.9683 Btu = 1,000 cal
1 ft lbf (foot pound force) = 1.3558 J = 0.1383 kp m = 3.766x10-7 kWh = 3.238x10-4 kcal = 1.285x10-3 Btu
1 hp h (horse power hour) = 2.6846x106 J = 0.7457 kWh
1 erg = 1 (g cm2)/s2 = 10-7 J
1 eV = 1.602x10-19 J
1 Q = 1018 Btu = 1.055x1021 J
1 Quad = 1015 Btu
1 Therm = 100,000 Btu
