Joule

Joule (J se darshawat baa) ek unit baa energy ke, jo International System of Units (SI) me use kaila jaala.

SI base unit ke roop me, ek joule barabar baa ek kilogram multiplied by metre squared per second squared:  
1 J = 1 kg⋅m²⋅s⁻²

Ek joule utna energy baa jitna kaam tab hoela jab 1 newton ke bal ek object ke 1 metre ke doori tak us direction me le jaala. Ii energy us condition me bhi samaan hoela jab 1 ampere ke electric current ek ohm ke resistance se 1 second tak guzarta baa — ii energy heat ke roop me dissipate ho jaala.

Ii unit ke naam James Prescott Joule (1818–1889), ek English physicist ke naam par rakh gais baa.
