1mA=0.00 1A， 1mA.h=3.6J .

100 mah = 360 joules.

1000 mA. hr = 3600 Joules.

brief introduction

In a pure resistance circuit, other formulas for calculating the heat of the circuit can be derived from the formula of Joule's law. However, it should be noted that the formula of Joule's law is applicable to all circuits, while the derived formula is only applicable to pure resistance circuits.

The International System of Units uses Joule (J) to express the unit of work or energy. 1 Joule is equal to 1 Newton force direction movement 1 meter; Is electrically equal to 1W? S, that is, when the current of 1A flows through the resistor of 1ω, the energy released in 1 sec.
