This will depend on the AC that you are using and how much you are running it. The more you run it, the more it will use.

You cannot since the units of measurement are incompatible. Apart from the fact that ton hour per hour is simply ton.

One ton of air conditioning capacity is equivalent to 12,000 British Thermal Units (BTU) per hour. A 3-ton air conditioning unit therefore has a cooling capacity of 36,000 BTU per hour.
Ah, what a lovely question! One ton is equal to 12,000 British Thermal Units per hour (BTU/hr) or 3.517 kilowatts. Isn't that just a happy little conversion to know? Just remember, whether it's tons or LRA, every unit has its own unique beauty.
Square metres are an area, a ton is a mass the units are incompatible.
One ton of cooling capacity is equivalent to 12,000 British Thermal Units (BTU) per hour. This measurement is commonly used in the heating, ventilation, and air conditioning (HVAC) industry to denote the cooling power of air conditioning units. Thus, if you have a system rated at one ton, it can remove 12,000 BTU of heat from a space each hour.
In the English units, there are 2000 pounds in a ton (also known as a short ton). As there are 1000 kilograms in a "tonne", a ton is equal to about 0.9072 tonnes.
A one ton heat pump typically has around 12,000 British Thermal Units (BTUs) per hour of heating or cooling capacity.
