Question

Express 1MW power in a system whose fundamental units are 10kg, 1dm and 1minute.

Answer 1

Units of power

P = W = J/s = (N*m)/s = (kg*m/s^2 * m) / s = kg*m^2/s^3

Conversion for 1 Watt

1 W = 1 kg*m^2/s^3 * (1 (10kg) / 10 kg) * (1 dm/10 m)^2 * (60 s / 1 min)^3 = 216 (10kg)*dm^2/min^3

1 Megawatt = 1000000 Watt = 216000000 (10 kg)*dm^2/min^3
