[Stoves] Cooking fuel equivalents

[Sharon Gordon]

Does anyone know of a table where I could find information on how to figure out how much of one cooking fuel equals another?

Say you have one kilogram of hardwood.  What would be an equivalent amount of:

minutes of low/med/high usage of one burner on an electric stove top
minutes of usage of an electric oven at a certain temperature
minutes of low/med/high usage of a gas burner
minutes of usage of a gas oven at a certain temperature
and similar for other gas, liquid or solid fuels ?
