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 .
Both sides of the equation have the dimensions of power, measured in watts in the International System of Units; hence the original name "watt balance". The product , also called the geometric factor, is not trivially equal in both calibration steps. The geometric factor is only constant under certain stability conditions on the coil.
g is acceleration due to gravity, approximately 9.81 m/s 2. To obtain power in units of watts, that is, SI units, the mass must be expressed in kilograms and the time in seconds. American football coaches use a slight variation of this test. In the football stair climb test the athlete runs up twenty steps four at a time. [6]
Families scrambling for answers. Since September, the 50 men have appeared, one after the other, in front of the court in Avignon. Usually in rape cases character investigations can take several days.
For a decade following his debut with the Rockies in 2013, Arenado’s all-world defense and potent bat kept him comfortably in the inner circle of elite players at his position.
The dimension of power is energy divided by time. In the International System of Units (SI), the unit of power is the watt (W), which is equal to one joule per second. Other common and traditional measures are horsepower (hp), comparing to the power of a horse; one mechanical horsepower equals about 745.7 watts.
