1. What is BTU to Tons Cooling Conversion?

Definition: This calculator converts cooling capacity from BTU/h (British Thermal Units per hour) to tons of refrigeration.

Purpose: It helps HVAC professionals and engineers convert between these common units of cooling capacity measurement.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( T \) — Tons of cooling
• \( Q \) — Cooling capacity in BTU/h

Explanation: One ton of cooling equals 12,000 BTU/h, based on the amount of heat needed to melt one ton of ice in 24 hours.

3. Importance of This Conversion

Details: HVAC systems are often rated in tons, while heat loads are calculated in BTU/h. This conversion is essential for proper system sizing and specification.

4. Using the Calculator

Tips: Simply enter the BTU/h value to get the equivalent in tons of cooling. The value must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why is 12,000 BTU/h equal to one ton?
A: It originates from the amount of heat required to melt one ton (2000 lbs) of ice in 24 hours (288,000 BTU/24h = 12,000 BTU/h).

Q2: Is this conversion exact?
A: Yes, the 12,000 BTU/h = 1 ton relationship is a defined standard in the HVAC industry.

Q3: What's a typical residential AC unit size?
A: Most homes have 1.5 to 5 ton units (18,000 to 60,000 BTU/h).

Q4: How do I calculate BTU requirements for a space?
A: Use our BTU Calculator tool or consult HVAC Manual J calculations.

Q5: Does this apply to both cooling and heating?
A: The ton unit is specifically for cooling capacity. Heating capacity is typically measured only in BTU/h.
