Convert Newton-metre to Watt-hour
1 newton-metre = 0.0002777778 watt-hour (Wh). For example, 10 newton-metre = 0.002777778 watt-hour and 100 newton-metre = 0.02777778 watt-hour. Type any value below to convert newton-metre to watt-hour 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.
Newton-metre to Watt-hour conversion formula
To convert newton-metre to watt-hour, multiply by 0.0002777778:
watt-hour = newton-metre × 0.0002777778
Going the other way, 1 watt-hour = 3,600 newton-metre, so
newton-metre = watt-hour × 3,600.

About newton-metre and watt-hour
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.
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.
