Multiple conversions
To convert from Watt-minute (Wm) to Watt-second (Ws), use the following formula:
Watt-second (Ws)
= 60× Watt-minute (Wm)
To convert from Watt-minute (Wm) to Watt-hour (Wh), use the following formula:
Watt-hour (Wh)
= 60 × 160 × 60× Watt-minute (Wm)
= 0.016666666666666666667× Watt-minute (Wm)
To convert from Watt-minute (Wm) to Milliwatt-hour (mWh), use the following formula:
Milliwatt-hour (mWh)
= 60 × 13.6× Watt-minute (Wm)
= 16.666666666666666667× Watt-minute (Wm)
To convert from Watt-minute (Wm) to Kilowatt-hour (kWh), use the following formula:
Kilowatt-hour (kWh)
= 60 × 160 × 60 × 1000× Watt-minute (Wm)
= 0.000016666666666666666667× Watt-minute (Wm)
To convert from Watt-minute (Wm) to Megawatt-hour (MWh), use the following formula:
Megawatt-hour (MWh)
= 60 × 160 × 60 × 106× Watt-minute (Wm)
= 1.6666666666666666667× 10-8× Watt-minute (Wm)
To convert from Watt-minute (Wm) to Gigawatt-hour (GWh), use the following formula:
Gigawatt-hour (GWh)
= 60 × 160 × 60 × 109× Watt-minute (Wm)
= 1.6666666666666666667× 10-11× Watt-minute (Wm)
To convert from Watt-minute (Wm) to Joule (J), use the following formula:
Joule (J)
= 60× Watt-minute (Wm)
To convert from Watt-minute (Wm) to Kilojoule (kJ), use the following formula:
Kilojoule (kJ)
= 60 × 11000× Watt-minute (Wm)
= 0.06× Watt-minute (Wm)
To convert from Watt-minute (Wm) to Megajoule (MJ), use the following formula:
Megajoule (MJ)
= 60 × 1106× Watt-minute (Wm)
= 0.00006× Watt-minute (Wm)
To convert from Watt-minute (Wm) to Gigajoule (GJ), use the following formula:
Gigajoule (GJ)
= 60 × 1109× Watt-minute (Wm)
= 6× 10-8× Watt-minute (Wm)
To convert from Watt-minute (Wm) to calorie (cal), use the following formula:
calorie (cal)
= 60 × 14.184× Watt-minute (Wm)
= 14.340344168260038241× Watt-minute (Wm)
With 14.184 is the ratio between the base units calorie (cal) and Joule (J).
To convert from Watt-minute (Wm) to Kilocalorie (kcal), use the following formula:
Kilocalorie (kcal)
= 60 × 14.184 × 11000× Watt-minute (Wm)
= 0.014340344168260038241× Watt-minute (Wm)
With 14.184 is the ratio between the base units calorie (cal) and Joule (J).
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:
