Unfortunately, the question as phrased is meaningless. A watt or kilowatt is a measure of voltage times current - one kilovolt at one amp of current dissipates one kilowatt of energy, but the same kilovolt at one tenth of an amp of current only dissipates 100 watts.
Here's the formula:
Watts = Volts * Amps
Liter ia a unit of volume; 1 m3=1 000 L Nanometer is a unit of length; 1 nm=10-9 m
A millimetre is a unit of distance. A pint is a unit of capacity. The two units are therefore incompatible.
1 Astronomical Unit = 149,598,000 kilometers.
A square metre is a unit of area. An inch is a unit of distance. The two units are therefore incompatible.
The volume of 1 unit can vary depending on the system of measurement being used. In the metric system, 1 unit typically refers to 1 liter of water, as the liter is the base unit for volume. Therefore, 1 liter of water is equivalent to 1 unit in the metric system.
