The SI unit of mass is the kilogram, which is denoted by the symbol kg.
The kilogram is currently defined by taking the fixed numerical value of the Planck constant h to be 6.62607015 × 10−34 when expressed in the unit J⋅s, which is equal to kg⋅m2⋅s−1, where the metre and the second are defined in terms of c and Δ νCs.
