How to Convert Kilohertz to Revolutions/Hour

To convert from Kilohertz (kHz) to Revolutions/Hour (rph), multiply the value by 3,600,000.

Formula: rph = kHz × 3,600,000

Reverse: kHz = rph × 2.777778e-7

Step-by-Step Example

Start with your value in Kilohertz. For example: 5 kHz
Multiply by the conversion factor: 5 x 3,600,000
The result is: 18,000,000 rph

About Kilohertz

The kilohertz (kHz) is a unit of frequency. One kilohertz equals 1000 hertzs. UnitConvertLab converts it against every other frequency unit using this exact definition, so results are reproducible to full double precision rather than rounded lookup tables.

Common uses: frequency calculations, engineering and science, education.

About Revolutions/Hour

The revolutions/hour (rph) is a unit of frequency. One revolutions/hour equals 0.0002777777778 hertzs. UnitConvertLab converts it against every other frequency unit using this exact definition, so results are reproducible to full double precision rather than rounded lookup tables.

Common uses: frequency calculations, engineering and science, education.
