Some of the ones that might apply here are: > > - Volts > - Coulombs > - Watts > - Amperes > - Seconds > - Joules No, these are not all fundamental. 1 Joule == 1 newton * 1 meter The newton isn't fundamental either. It is defined in terms of meters, seconds, and kilograms. So if I've not mucked something up, 1 J == 1 m*kg*m/s/s. Units get ugly when arbitrary powers of 10 get thrown in, and worse with random odd constants. Amperes have a 2.0e-7 in the definition. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org Please read the FAQ at http://www.tux.org/lkml/
