To determine the amps for a 1 ton cooling unit at 480 Volts, you would need to know the power rating of the unit in Watts. Once you have the Watts, you can use the formula Amps = Watts/Volts to calculate the amperage.
When talking about refrigeration, a ton is a unit of power. To quote wikipedia:"In North America, a standard ton of refrigeration is 12,000 BTU/h = 200 BTU/min ≈ 3,517 W. This is approximately the power required to melt one short ton (2,000 lb) of ice at 0 °C in 24 hours, thus representing the delivery of 1 ton of ice per day." (http://en.wikipedia.org/wiki/Ton)

It the unit is watts, megawatts is millions of watts, so to convert watts to megawatts, multiply the number of watts be 1,000,000.
1.5 ton convert kw
kW x 1,000 = watts
Watts x 0.001341 = hp
3KW
To convert watts to kilowatts, divide by 1000. Therefore, 255 watts is equal to 0.255 kilowatts.
cooling capacty one ton is how much watts
Watts are the product of amps x volts.
No. Watts = Volts x Amps Watts does not directly convert to volts.
