Estimate the air conditioner capacity a space needs.
A cooling load per square foot is multiplied by the area, then converted to tons assuming 12,000 BTUs per ton. A minimum half-ton step avoids undersizing. AC units come in fixed tonnage steps, so a properly sized unit removes humidity without wasteful short cycling.
AC Size in Tons
Tons = area x BTU/sq ft / 12000

This calculator takes 2 inputs: Area to cool, Cooling load per sq ft. The pre-filled defaults are a realistic starting point — replace them with figures from your own environment for a result you can act on.
