BTU (Btu) - British thermal Unit - additionally known as a "heat unit" in United says Calorie Joule

### BTU - British thermal Unit

The unit of warmth in the royal system - the BTU - is

the quantity of heat forced to raise the temperature the one pound of water through 1oF (58.5oF - 59.5oF) at sea level (30 inch of mercury). 1 Btu (British heat unit) = 1055.06 J = 107.6 kpm = 2.931 10-4 kWh = 0.252 kcal = 778.16 ft.lbf = 1.0551010 ergs = 252 cal = 0.293 watt-hours

An item making use of one kilowatt-hour of electrical power generates 3412 Btu.

one hundreds thousand (105) Btu are called a therm

### Calorie

A calorie is commonly identified as

the quantity of heat required to advanced the temperature the one gram the water 1 oC the kilogram calorie, big calorie, food calorie, Calorie (capital C) or simply calorie (lowercase c) is the amount of power required come raise the temperature that one kilogram of water through one level Celsius 1 calorie (cal) = 1/860 global watthour (Wh) 1 kcal = 4186.8 J = 426.9 kp m = 1.163 10-3 kWh = 3.088 ft lbf = 3.9683 Btu = 1000 cal

Be mindful that different definitionsexists - in short:

Thermochemical calorie 4°C calorie 15°C calorie 20°C calorie median calorie International steam Table calorie (1929) International steam Table calorie (1956) IUNS calorie (Committee on Nomenclature of the international Union the Nutritional Sciences)

The calorie is outdated and also commonly replaced by the SI-unit Joule.

### Joule

The unit of warmth in the SI-system the Joule is

a unit of energy equal to the work-related done as soon as a pressure of one newton acts v a street of one meter 4.184 joule the heat power (or one calorie) is compelled to progressive the temperature that a unit load (1 g) the water indigenous 0oC to 1oC, or indigenous 32oF come 33.8oF 1 J (Joule) = 0.1020 kpm = 2.778 10-7 kWh = 2.389 10-4 kcal = 0.7376 ft.lbf = 1 kg.m2/s2 = 1 watt second = 1 Nm = 9.478 10-4 Btu
