1. What is a BTU to Tons Calculator?

Definition: This calculator converts cooling capacity from British Thermal Units per hour (BTU/h) 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
• \( B \) — BTU per hour (BTU/h)

Explanation: One ton of refrigeration equals 12,000 BTU per hour. The formula divides the BTU value by 12,000 to convert to 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 BTU value (must be > 0) and the calculator will automatically compute the equivalent tons.

5. Frequently Asked Questions (FAQ)

Q1: Why is the conversion factor 12,000?
A: One ton of refrigeration was historically defined as the cooling power of one ton of ice melting over 24 hours, which equals 12,000 BTU per hour.

Q2: Is this calculator for heating or cooling?
A: Primarily for cooling capacity, though the same conversion applies to heating BTUs when expressed as equivalent tons of cooling.

Q3: How precise is this conversion?
A: The 12,000:1 ratio is standard in the HVAC industry, though some systems may have slight variations in actual performance.

Q4: 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).

Q5: Can I convert tons back to BTU?
A: Yes, simply multiply tons by 12,000 to get BTU/h.
