text: Thus, the kilogram is defined in terms of the three defining constants Δν Cs , c, and h because, on the one hand, these three defining constants respectively define the units Hz, m/s, and J⋅s,[Note 35] while, on the other hand, the kilogram can be written in terms of these three units, namely, kg = (Hz)(J⋅s)/(m/s)2.[Note 36]
