It depends how far you lift it.
If you lift one metric tonne (1000kg) through 1metre,
1000kg = 10,000N
10000 * 1 = 10000 Joules
1 joule = 0.000239005736 Calories
10,000 joules = 2.39 Calories
(note, I'm using a capital C for Calories indicating kilo-calories. This is the conventional nutritional energy unit).
Cheers.

If you lift 1 tonne to a height 'h' (say)
work done = mgh
= 1000*9.8*h
= 9800*h joules
= (9800*h)/4.1858 calories
= 2341.248985*h calories

you will need a fork lift to lift one ton. So i'd say minimal calories as it doesn't require much to push a button!

Need to know how high to work out the total work done.
Happy New Year.

Depends on how high you lift it?

You have to specify how high you lift it!

it would definitely depend on how high you carry it. or with how much effort. how many repitions. it depends on a lot of variables.
