It depends on the (EER) Energy Efficiency Ratio,which is capacity divided by watts.
Example 35000 btus / 2500 watts = 14 EER
If you know the capacity,btus and EER you can calculate the watts, capacity / EER
Example 35000 btus / 14 EER = 2500 watts.

EER is determine by testing the air conditioner at Department of Energy Guidelines, which are
80° drybulb 67° wetbulb indoor and 95° and 82° drybulb outdoor.
