(SI); it is equal to the workdoneby aforceof onenewtonacting through onemetre. Named in honour of the English physicistJames Prescott Joule, it equals 107ergs, or approximately 0.7377 foot-pounds. In electrical terms, the joule equals one watt-second—i.e., the energy released in one ...

Convert solar radiation from Joule per cm square to Watt per meter^2? I have solar radiation data in the units of Joule per cm^2 (joule per square centimeter) measured hourly. I want to use this data in evapotranspiratin calculation which requires radiation units as Watt per meter squared...
Watts are never equivalent to joules, because watt is a unit for *power* and joule is a unit for *energy*. But why are newton-metres not equivalent to joules? By anon274569 — On Jun 12, 2012 In daily use terms, one 99999 watt lamp, how many joules is it equivalent to? Is it...
The energy conversion of joules to BTU is given by the formula:E(BTU) = E(J) / 1055.05585262 = 0.00094781712 ⋅ E(J)For example: when E=500J,E(BTU) = 500J / 1055.05585262 = 0.473909 BTUJoules to BTU conversion tableEnergy (J)Energy (BTUIT) 1 J 0.000948 BTU 2 J 0.001896 BTU ...
To be called a Joule Thief I think a circuit needs to be able to start when it's input voltage is below 1.0 Volt. That's because one volt is one of the definitions of a dead single cell battery. So if a circuit can start up on less than that it's stealing energy that would hav...
