1. What is a BTU and Tonnage Calculator?

Definition: This calculator converts cooling capacity from BTU/h to tons of refrigeration.

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

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( T \) — Tonnage (tons of refrigeration)
• \( Q \) — Cooling capacity (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 Tonnage Conversion

Details: This conversion is essential for sizing HVAC equipment, comparing system capacities, and ensuring proper cooling system design.

4. Using the Calculator

Tips: Simply enter the BTU/h value (must be > 0) and the calculator will instantly show the equivalent tonnage.

5. Frequently Asked Questions (FAQ)

Q1: Why 12,000 BTU/h equals 1 ton?
A: This originates from the amount of heat needed to melt one ton of ice in 24 hours (288,000 BTU/24h = 12,000 BTU/h).

Q2: What's a typical residential AC tonnage?
A: Most homes need 1-5 tons (12,000-60,000 BTU/h) depending on size and climate.

Q3: How precise is this conversion?
A: The 12,000:1 ratio is standard, though actual system performance may vary based on efficiency.

Q4: Can I convert tons back to BTU?
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 systems are typically rated directly in BTU/h rather than tons.
