How many calories do you need to burn to lose 1 kilogram of weight?

I would like to know about the calorie-weight relationship. This is for me to be clear about how much I'm losing as I increase my activities and reduce my food intake or see that I eat more healthy. If anyone can help me out I would appreciate it.

7700

1lb = 3500 calories

1lb = 2.2kg

sooooo..... pay attention this is highly sophisticated math here 

3500 x 2.2 = 7700

This is perfectly correct math :) and apologies for being picky, however to prevent confusion, it's 1kg = 2.2lb.

So yes, 7700 cals need to be burned in order to lose 1kg of weight (in theory).

Thank you all

 In theory indeed. Should we have expanded to say that it's 7700 kcal in versus kcal out deficit to lose 1kg of weight? Advice and explanation did not seem to be wanted.
