POWER RATE WORKSPACE

Power Converter

Convert watts, kilowatts, megawatts, mechanical horsepower, metric horsepower, and BTU IT per hour without confusing power with energy.

Reviewed reference factorsValues stay in this browser tabNon-negative power rates only; energy use, efficiency, demand profile, and cost are not estimated.

Conversion input

Convert an energy-transfer rate

Enter a known power rating and select the convention printed on the source. Mechanical horsepower and metric horsepower remain separate because their watt factors are not identical.

Find a unit6 / 6

Filter by unit name, symbol, or code. Your current selections remain available.

Known value0 / 80

Enter a non-negative power rate. Confirm the horsepower or BTU convention before relying on a converted equipment rating.

Convert from

Choose the unit attached to the value you entered.

Convert to

Choose the unit required for your report, estimate, or comparison.

Displayed precision

Choose the maximum decimal places shown. This does not increase source accuracy.

Conversion runs locally after the active reference catalogue loads.

Conversion result

Load the 75 kW example or enter a power rate to compare watt-based equivalents.

What this tool delivers

Power rates converted on a watt basis

The workspace changes units for an existing rate and does not infer runtime, energy consumption, useful output, or cost.

What it converts

Converts one power magnitude among watt multiples, two labelled horsepower conventions, and BTU IT per hour.

What you provide

A non-negative power value, an exact source convention, a destination unit, and appropriate display precision.

What you receive

A selected power result, the watt conversion path, every available equivalent, and a CSV export.

Calculation method

How every power unit passes through watts

The input is multiplied by its watts-per-unit factor and the resulting watt value is divided by the destination factor. The horsepower and BTU labels remain explicit so convention differences cannot disappear behind rounding.

Quick answers

Power Converter questions

Are mechanical and metric horsepower identical?

No. Mechanical horsepower and metric horsepower are separate conventions with different watt factors. The selector labels mechanical horsepower as hp and metric horsepower as PS, and the result table keeps both. Match the source plate, standard, or specification instead of choosing horsepower from the word alone.

Can this convert kilowatts to kilowatt-hours?

Not without elapsed time. A kilowatt is a power rate, while a kilowatt-hour is an amount of energy. Multiply average kilowatts by operating hours to estimate kilowatt-hours, then account separately for changing loads during the interval, efficiency, standby consumption, and measurement uncertainty when those factors matter.

Does converted input power equal useful output power?

Not necessarily. This tool changes only the unit label and numeric scale of the supplied power. Motors, engines, heaters, inverters, and other equipment can lose energy or report ratings at different boundaries. Confirm whether the source means input, shaft, thermal, apparent, or another defined power before comparison.
