1. What is BTU to Tons 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 refrigeration
• \( Q \) — Cooling capacity in BTU/h

Explanation: One ton of refrigeration equals 12,000 BTU/h, so we divide the BTU value by 12,000 to get the equivalent in tons.

3. Importance of BTU to Tons Conversion

Details: This conversion is essential for sizing air conditioning systems, comparing cooling capacities, and ensuring proper equipment selection.

4. Using the Calculator

Tips: Simply enter the cooling capacity in BTU/h. The calculator will automatically convert it to tons of refrigeration.

5. Frequently Asked Questions (FAQ)

Q1: Why is 1 ton equal to 12,000 BTU/h?
A: This originates from the amount of heat needed to melt one ton of ice in 24 hours, which equals 12,000 BTU/h.

Q2: What's a typical residential AC capacity?
A: Most homes have systems between 1.5 to 5 tons (18,000 to 60,000 BTU/h).

Q3: How do I find my system's BTU rating?
A: Check the manufacturer's specifications on the unit's nameplate or in the manual.

Q4: Is this conversion exact?
A: Yes, 12,000 BTU/h is the exact definition of 1 ton of refrigeration.

Q5: What about other units like kW?
A: 1 ton ≈ 3.517 kW. Use our kW to Tons converter for those calculations.
