The 21 pages that link to Watt, each with the reason it gives.

• AmpereCompared with: Electrical power depends on current as well as voltage.

• VoltCompared with: A watt measures energy transfer per time, not potential difference.

• HorsepowerCompared with: Watts provide the SI reference used to compare horsepower definitions.

• CandelaCompared with: A watt measures radiant power without the visual weighting built into the candela.

• British thermal unitCompared with: A watt measures the rate of energy transfer, unlike the Btu’s energy quantity.

• CandlepowerCompared with: Electrical wattage is not a direct measure of a lamp’s candlepower.

• Newton-secondCompared with: Power measures energy transfer rate, not impulse or momentum.
