What 1 ton air conditioner mean?

A 1-ton air conditioner refers to the cooling capacity of the unit, which is defined as the ability to remove heat equivalent to one ton of ice melting in a 24-hour period. This translates to about 12,000 British Thermal Units (BTUs) per hour. The term originates from historical practices where large blocks of ice were used for cooling, and it helps consumers understand the cooling power of the air conditioner in relation to the size of the space it can effectively cool.
