Kilometer = 1000m
Quart = 0.000946m³
Force = mass × acceleration
=> F = ma
Putting units:
Newton = kg.m/s² or kg.m.s^-2 _____(1)
Pressure = force/area
Putting units:
Pascal = Newton/m²
=> Pascal = kg.m.s^-2.m² [from (1)]
=> Pascal = kg.m^-1.s^-2
Work = force × displacement
=> W = Fs
Putting units:
Joule = Newton.m
=> Joule = kg.m.s^-2.m [from (1)]
=> Joule = kg.m².s^-2 ______(2)
Power = work/time
Putting units:
Watt = joule/s
=> Watt = kg.m².s^-2/s [from (2)]
=> Watt = kg.m².s^-3 ______(3)
Horsepower = 746 watt
=> Horsepower = 746kg.m².s^-3 [from (3)]
