no watt is a measurement of power where as if you meant joule that is a measurement of energy which are not the same thing
Joules (J), the same for any measurement of energy.

There is no "measurement of light". The units used depend on what you want to measure: its speed, frequency, wavelength, energy per photon, etc.
The energy unit is the Joule, J in the International System of units;Calorie is also an energy unit;British Thermal units, BMU.1 BTU = 1055 J1 calorie = 4.18 J
Units of measurement are useful to rationally measure anything.
