Convert Watt-hour to Newton-metre
1 watt-hour = 3,600 newton-metre (N·m). For example, 10 watt-hour = 36,000 newton-metre and 100 watt-hour = 360,000 newton-metre. Type any value below to convert watt-hour to newton-metre both ways — it runs entirely in your browser.
Torque vs energy: Newton-metre (N·m) is used both as a unit of ENERGY — where 1 N·m = 1 joule exactly — and as a unit of TORQUE (a twisting force × distance). This page converts the ENERGY meaning, so the figures above are correct for work and heat. A newton-metre of torque is a different physical quantity and does NOT convert into joules, kilowatt-hours or calories.
Watt-hour to Newton-metre conversion formula
To convert watt-hour to newton-metre, multiply by 3,600:
newton-metre = watt-hour × 3,600
Going the other way, 1 newton-metre = 0.0002777778 watt-hour, so
watt-hour = newton-metre × 0.0002777778.

About watt-hour and newton-metre
Watt-hour: A watt-hour is the energy of one watt sustained for one hour — exactly 3,600 joules. Commonly used to rate battery capacity.
Newton-metre: A newton-metre is one newton applied over one metre. As a unit of ENERGY it is identical to the joule (1 N·m = 1 J); as a unit of TORQUE it measures rotational effort — a different physical quantity that does not convert into joules, kWh or calories.
Frequently asked questions
- How many newton-metre are in 1 watt-hour?
