A Watt-minute (Wm) is a unit of energy that measures the total energy consumed when one watt of power is applied for exactly one minute.
The plural form is Watt-minutes.
To make it easier to understand, think of it like filling a bucket with a hose. If a watt is the speed at which water flows, a Watt-minute is the total amount of water in the bucket after the hose has been running for one minute.
One Watt-minute is precisely equal to 60 Joules (J).
This conversion is simple because a watt is defined as one joule per second (1 W = 1 J/s). Since there are 60 seconds in a minute, the calculation is straightforward:
1 Watt-minute = 1 Watt × 60 seconds = 60 Joules
This simple formula makes the Wm to J conversion easy to remember for any energy calculation.
While you're more likely to see Watt-hours (Wh) or kilowatt-hours (kWh) on your electricity bill, the Watt-minute is an essential unit for more precise energy measurement in specific fields.
It's most useful in situations where energy is tracked over short intervals, such as:
