1. What is a BTU/hr to Tons Cooling Calculator?

Definition: This calculator converts cooling capacity from BTU per hour to tons of refrigeration.

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

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( T \) — Tons of cooling
• \( Q \) — BTU per hour (BTU/h)

Explanation: One ton of cooling equals 12,000 BTU per hour, so we divide the BTU value by 12,000 to get tons.

3. Importance of This Conversion

Details: HVAC systems are often rated in tons, while heat loads are calculated in BTU/h. This conversion bridges these measurement systems.

4. Using the Calculator

Tips: Simply enter the BTU per hour value. The calculator will automatically divide by 12,000 to give you tons of cooling.

5. Frequently Asked Questions (FAQ)

Q1: Why 12,000 BTU per ton?
A: This comes from the amount of heat needed 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 standard definition in the refrigeration industry.

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

Q4: How do I find my system's BTU rating?
A: Check the manufacturer's plate on the unit or consult specifications.

Q5: Does this account for efficiency (SEER)?
A: No, this is a direct capacity conversion. Efficiency affects power consumption, not capacity.
