The watt, kilogram, joule, and the second are part of the International System of Units (SI). The hour is not, though it is accepted for use with the SI.Since a watt equals one joule per second and because one hour equals 3600 seconds, one watt-hour per kilogram can be expressed in SI units as 3600 joules per kilogram.
The watt (symbol: W) is the unit of power or radiant flux in the International System of Units (SI), equal to 1 joule per second or 1 kg⋅m 2 ⋅s −3. [ 1 ] [ 2 ] [ 3 ] It is used to quantify the rate of energy transfer .
[1] [2] It was originally known as a watt balance because the weight of the test mass is proportional to the product of current and voltage, which is measured in watts . In June 2016, two months after the death of its inventor, Bryan Kibble , metrologists of the Consultative Committee for Units of the International Committee for Weights and ...
