1. What is a BTU to Cooling Tons Calculator?

Definition: This calculator converts cooling capacity from BTU 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 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 the equivalent in tons.

3. Importance of the Conversion

Details: HVAC systems are often rated in tons, while heat loads are calculated in BTU/h. This conversion is essential for proper system sizing and specification.

4. Using the Calculator

Tips: Simply enter the BTU per hour value. The calculator will automatically convert it to tons of cooling.

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 (288,000 BTU/day, which equals 12,000 BTU/h).

Q2: Is this conversion exact?
A: Yes, the 12,000 BTU/h to 1 ton ratio is a standard definition in the HVAC industry.

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

Q4: How do I calculate BTU requirements for a space?
A: Use our BTU Calculator tool or consult an HVAC professional for a Manual J calculation.

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