1. What is a BTU to Tons Calculator?

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, derived from the amount of heat needed to melt one ton of ice in 24 hours.

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 to get the equivalent in tons. The value must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why is the conversion factor 12,000?
A: This comes from the original definition of a ton of refrigeration - the heat absorption needed to melt one ton (2000 lbs) of ice in 24 hours.

Q2: How precise is this conversion?
A: The 12,000 BTU/h = 1 ton is a standard industry conversion, though actual system performance may vary slightly.

Q3: What's a typical residential AC capacity?
A: Most homes use 1.5-5 ton systems (18,000-60,000 BTU/h), depending on size and climate.

Q4: Can I convert tons back to BTU/h?
A: Yes, simply multiply tons by 12,000 to get BTU/h.

Q5: Does this apply to heating as well?
A: While the calculation works the same, heating capacity is typically expressed directly in BTU/h rather than tons.
