Tons to Kilowatts Conversion Calculator

Tons to Kilowatts Calculator

Enter power in refrigeration tons:

Result in kilowatts: kW

A tons to kilowatts calculator converts refrigeration capacity between tons of refrigeration (RT) and kilowatts (kW), essential for:
✅ HVAC system design
✅ Energy efficiency calculations
✅ International equipment specifications
✅ Cooling system power requirements

Key Definitions

Ton of Refrigeration (RT): Cooling capacity to melt 1 ton of ice in 24 hours
Kilowatt (kW): Metric unit of power (1 RT ≈ 3.51685 kW)

Conversion Formulas

1. Tons to Kilowatts

P (k W) = P (R T) \times 3.51685

Example:

Convert 5 tons to kW:
$5 \times 3.51685 = 17.584 kW$

2. Kilowatts to Tons

P (R T) = \frac{P (k W)}{3.51685}

Example:

Convert 10.55 kW to tons:
$10.55 \div 3.51685 \approx 3 RT$

Conversion Table (RT ⇆ kW)

Tons (RT)	Kilowatts (kW)
0.5 RT	1.758 kW
1 RT	3.517 kW
1.5 RT	5.275 kW
2 RT	7.034 kW
3 RT	10.551 kW
5 RT	17.584 kW
10 RT	35.168 kW
20 RT	70.337 kW

How to Use the Calculator

Enter Tons → Get kW (Multiply by 3.51685)
Enter kW → Get Tons (Divide by 3.51685)

Example Calculations:

7.5 tons to kW:
$7.5 \times 3.51685 = 26.376 kW$
21.101 kW to tons:
$21.101 \div 3.51685 \approx 6 RT$

Practical Applications

Air Conditioners: 3-ton unit ≈ 10.55 kW cooling capacity
Chillers: 100-ton chiller ≈ 351.685 kW power requirement
Heat Pumps: 5-ton system ≈ 17.58 kW heating/cooling capacity

Cooling Capacity Comparison

System Type	Capacity	kW Equivalent
Window AC Unit	1 RT	3.517 kW
Residential Central AC	3-5 RT	10.55-17.58 kW
Commercial Chiller	20-50 RT	70.34-175.84 kW
Industrial Refrigeration	100+ RT	351.69+ kW

FAQ

1. Why convert tons to kW?

🔹 For international compatibility (kW is SI unit)
🔹 To calculate electrical power requirements

2. How many kW is 1 ton?

✅ 1 RT = 3.51685 kW

3. What's the difference between cooling tons and kW?

🔹 Tons measure cooling capacity
🔹 kW measures power consumption

4. How to convert 2.5 tons to kW?

2.5 \times 3.51685 = 8.792 kW

5. Is higher tonnage more energy efficient?

❌ Not necessarily - efficiency depends on SEER/EER ratings
