A typical coal-fired power plant works at 10,500 Btu/kWh (3.1 kWh/kWh), an efficiency of 32–33%. [25] The centigrade heat unit (CHU) is the amount of heat required to raise the temperature of one pound (0.45 kg) of water by one Celsius degree. It is equal to 1.8 Btu or 1,899 joules. [26]

The therm (symbol, thm) is a non-SI unit of heat energy equal to 100,000 British thermal units (BTU), [1] and approximately 105 megajoules, 29.3 kilowatt-hours, 25,200 kilocalories and 25.2 thermies. One therm is the energy content of approximately 100 cubic feet (2.83 cubic metres) of natural gas at standard temperature and pressure .

This article gives a list of conversion factors for several physical quantities.A number of different units (some only of historical interest) are shown and expressed in terms of the corresponding SI unit.
is the power per unit length, in [W·m −1] is the thermal conductivity of the sample, in [W·m −1 ·K −1] is the exponential integral, a transcendent mathematical function is the radial distance to the line source
BMI. BMI measures a person’s weight compared to their height. It’s a simple division equation. Since it’s such a quick and easy way to get a rough idea of whether you have a healthy weight ...
The kilogram, symbol kg, is the SI unit of mass. It is defined by taking the fixed numerical value of the Planck constant h to be 6.626 070 15 × 10 −34 when expressed in the unit J⋅s, which is equal to kg⋅m 2 ⋅s −1, where the metre and the second are defined in terms of c and Δν Cs. —
