|Which is correct?
The ______ is the International System of Units’ (SI) standard unit of power. It’s named for James Watt, a Scottish inventor and mechanical engineer who developed the idea of horsepower.
This was kind of a trick question. You’d probably expect units of measurement named for people to be capitalized but that’s not the case. Like other units of measurement, “watt” is only capitalized as the symbol, “W.”
Here are a few other examples:
The newton (N), the SI unit of force, is named for Sir Isaac Newton.
The pascal (Pa), the unit of pressure, is named for Blaise Pascal.
