It’s another one of those weird non-metric units. In the world of air conditioning (or cooling in general), a “ton” is the amount of cooling you’d get from melting a ton (a short ton - that is 2000 pounds) of ice that’s already near its melting point. Air conditioners are usually rated in tons per day, with 1-5 tons about right for a typical apartment or house, depending on things like square footage and climate.

I’m the kind of person to argue the merits of the imperial system, and even I think that’s bonkers.

Wut? I though it was unit of power per mass of machine. Why, just why?

What do you think the metric system is based on? It’s the exact same thing.
0c is the temperature of water freezing (at sea level, etc.etc.)
100c is the temperature that water boils.
1 kilocalorie is the energy needed to raise the temperature of 1kg of water one degree.
You have to define energy in some way, and almost all of it is related to how it affects water.
Fingers.
Calories are not metric. And there are even two calories. Not as bad as 10 different inches, but use Joule(metric unit, Newton*meter) instead.
That makes sense actually. Thanks!

(side note, thank you for the explanation)
Ffs USA. YOU’RE ALREADY USING kW, JUST GO FULL METRIC ON POWER. Please I’m begging you.
COP = heat moved / power input
kW_out / kW_in = dimensionless value
An air-conditioner with a COP of 2 moves 2 kW of heat for every 1 kW of electrical power you put in.
This hurts so much to find out because the US is already using BTU/hr 🤢. What do you need yet another unit for power for?
You’re using W, BTU/hr and ton/day?
Like. Why are you doing this?
😭 look what they did to my boy (units)
