1. What is an AC Tonnage Calculator for India?

Definition: This calculator converts air conditioner cooling capacity from BTU/hr to tons, which is the standard measurement used in India's HVAC industry.

Purpose: Helps homeowners and HVAC professionals properly size air conditioning units for Indian homes and buildings.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( T \) — AC tonnage (tons)
• \( BTU \) — Cooling capacity (BTU per hour)

Explanation: 1 ton of cooling equals 12,000 BTU/hr. The formula converts BTU rating to standard tons used in India.

3. Importance of Proper AC Sizing

Details: Correct tonnage calculation ensures energy efficiency, proper cooling, and prevents overworking the AC unit.

4. Using the Calculator

Tips: Enter the AC unit's BTU rating (found on specification sheets). Common residential units range from 6,000 BTU (0.5 ton) to 24,000 BTU (2 ton).

5. Frequently Asked Questions (FAQ)

Q1: Why is tonnage important for AC units?
A: Tonnage determines cooling capacity. Undersized units won't cool properly, while oversized units short-cycle and waste energy.

Q2: What's a typical tonnage for Indian homes?
A: Most Indian bedrooms need 0.75-1 ton (9,000-12,000 BTU), while living rooms may need 1.5-2 tons (18,000-24,000 BTU).

Q3: How do I find my AC's BTU rating?
A: Check the model number/specs on the unit or manufacturer's website. It's often part of the model name (e.g., "18K" = 18,000 BTU).

Q4: Does this consider Indian climate conditions?
A: This is a basic conversion. For precise sizing, consult an HVAC professional who considers humidity, insulation, and local temperatures.

Q5: What's the difference between US and Indian tons?
A: Both use the same 12,000 BTU = 1 ton standard, but Indian ACs are often marketed by tonnage while US uses BTU more frequently.
