A coherent derived unit isdefined as a derived unit that, for a given system of quantities and for a chosen set of base units, is a product of powers of base units with no other proportionality factor than one. ... The InternationalSystem of Units (1960) was designed around the systemof coherence.

It meas that all SI units are derived from finite basic units with no other factor than one (1).
For example,
F=ma⇒1N =1kg×m/s^2. F=ma⇒1N = 1kg×m/s^2
W=Fs⇒1J=1N×mW=Fs⇒1J=1N×m
.
Well known coherent systems are SI, CGS and MKS (a subset of SI now). all metric units.
