Glossary » Units » Energy » Celsius-Heat Unit
Celsius-Heat Unit (Chu) is a unit in the category of Energy. This unit is commonly used in the UK, US unit systems. Celsius-Heat Unit (Chu) has a dimension of ML2T-2 where M is mass, L is length, and T is time. It can be converted to the corresponding standard SI unit J by multiplying its value by a factor of 1899.18.
Note that the seven base dimensions are M (Mass), L (Length), T (Time), Q (Temperature), N (Aamount of Substance), I (Electric Current), and J (Luminous Intensity).

Other units in the category of Energy include A.u. of Energy (Eh), Barrel Oil Equivalent (bboe), Bboe (barrel Oil Equivalent) (bboe), BeV (billion EV) (BeV), British Thermal Unit (ISO) (Btu (ISO)), British Thermal Unit (IT) (Btu (IT)), British Thermal Unit (mean) (Btu (mean)), British Thermal Unit (thermochemical) (Btu (therm.)), Calorie (15°C) (cal15), Calorie (4°C) (cal4), Calorie (diet Kilocalorie) (Cal, kcal), Calorie (IT) (International Steam Table) (cal (IT)), Calorie (mean) (calmean), Calorie (thermochemical) (cal (therm.)), Coulomb Volt (C-V), Cubic Centimeter-Atm (cm3-atm), Cubic Foot Atm (ft3-atm), Electronvolt (eV), Erg (erg), Foot-Pound Force (ft-lbf), Foot-Poundal (ft-pdl), Gigaelectronvolt (GeV), Gram Calorie (gram-cal), Hartree (Eh), Horsepower (550ft-Lbf/s)-Hour (Hp-h), Inch Pound Force (in-lbf), Joule (J), Kilocalorie (15°C) (kcal15), Kilocalorie (4°C) (kcal4), Kiloelectronvolt (keV), Kilojoule (kJ), Kiloton TNT Equivalent (kt (TNT)), Kilowatt-Hour (kWh), Megaelectronvolt (MeV), Megajoule (MJ), Megaton TNT Equivalent (Mt (TNT)), Newton Meter (N-m), Q Unit, Quad (quad), Quadrillion (quad), Rydberg (Ry), Tce (tonne Coal Equivalent) (tce), Therm (EEG), Therm (US), Thermie (15°C) (th15 °C), Toe (tonne Oil Equivalent) (toe), Ton TNT Equivalent (ton (TNT)), Tonne Coal Equivalent (tce), Tonne Oil Equivalent (toe), and Watt Hour (Wh).
