What is Power Converter?
A power converter translates the rate of energy transfer among watts, kilowatts, megawatts, mechanical horsepower, metric horsepower, BTU per hour, and tons of refrigeration.
Power describes how quickly energy is used, delivered, or removed. One watt equals one joule per second. Energy accumulates over time, which is why a 2 kW appliance running for three hours uses 6 kWh, not 2 kWh.
This tool distinguishes mechanical horsepower from metric horsepower and includes HVAC-oriented rates. These similarly named units are not interchangeable, so their labels and contexts should be preserved.
Why Use This Tool?
Use power conversion to compare motors, generators, appliances, engines, heating equipment, and cooling capacity. A motor may be sold in horsepower while electrical documentation uses kilowatts.
The all-unit table makes cross-industry ratings easier to inspect, but it does not calculate electrical current, fuel use, system efficiency, or actual cooling load.
- Convert watts, kilowatts, and megawatts
- Compare mechanical and metric horsepower
- Translate BTU/h and refrigeration tons
- Check motor, appliance, and HVAC ratings
How Does This Tool Work?
Every conversion passes through watts. The source value is multiplied by its watt factor and divided by each destination factor. Mechanical horsepower is represented as about 745.6998715822702 W, while metric horsepower is 735.49875 W.
One BTU/h is represented as 0.29307107 W. One ton of refrigeration is 3,516.8528 W, equivalent to 12,000 BTU/h within the factors used. Refrigeration ton is a cooling rate, not a unit of mass.
Understanding Your Results
Each row reports the same ideal power rate in another unit. For example, 1 mechanical hp is about 0.7457 kW, whereas 1 metric horsepower is about 0.7355 kW.
Rated input, rated output, peak power, continuous power, and cooling capacity can describe different aspects of equipment. Unit conversion does not make those ratings directly equivalent unless their definitions and test conditions match.
Why Tracking This Matters
Correct power comparisons support equipment sizing, electrical planning, engine evaluation, and HVAC communication. Confusing power with energy or one horsepower definition with another can distort operating and cost estimates.
Benefits of Using Power Converter
- Seven electrical, mechanical, thermal, and HVAC units
- Separate mechanical and metric horsepower
- BTU/h and refrigeration-ton support
- Watt-based consistent conversion
- Instant private calculations
- Useful for equipment comparison and planning
How Is the Result Calculated?
All unit conversions use watts as the shared base. To calculate energy, multiply power by operating time in compatible units.
destination power = source power × source-to-watt factor ÷ destination-to-watt factor; E = P × t
- P
- Power or energy-transfer rate.
- E
- Energy accumulated over the operating period.
- t
- Time for which the power is sustained.
- 1 mechanical hp ≈ 745.6998716 W
- 1 metric hp = 735.49875 W
- 1 refrigeration ton ≈ 3,516.8528 W
Tips for Better Results
- Identify the horsepower standard before converting.
- Distinguish equipment input power from useful output power.
- Use kWh, not kW, when discussing accumulated electricity use.
- Treat refrigeration tons as cooling capacity, not mass.
- Apply efficiency and load factor separately.
- Follow qualified engineering guidance when sizing electrical or HVAC systems.

Conclusion
Use the power converter to compare watt-based, horsepower, thermal, and cooling rates while preserving each rating’s context.
For real equipment decisions, distinguish input from output, power from energy, and nominal capacity from actual performance under operating conditions.
