Watt Hour (Wh) is a unit in the category of Energy. It is also known as watt hours. Watt Hour (Wh) 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 3600.
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.)), Celsius-Heat Unit (Chu), 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), and Tonne Oil Equivalent (toe).
