With the Speed Converter tool, you can quickly and accurately compare different speeds. Whether you want to convert kilometres per hour to miles per hour or need metres per second for a technical calculation, this speed calculator does it instantly for you.

Speed is expressed in different ways around the world. This tool prevents calculation errors and saves time.

Supported speed units

The tool supports the most commonly used units:

• Kilometres per hour (km/h) – standard in Europe
• Miles per hour (mph) – used in, among other places, the US and the UK
• Metres per second (m/s) – for scientific and technical use

When should you convert speed?

Converting speeds is useful for:

• driving abroad
• sports and running
• physics and engineering
• traffic regulations
• international specifications

Conversion formulas

The tool uses fixed, reliable formulas:

• mph = km/u ÷ 1,609344
• km/u = mph × 1,609344
• m/s = km/u ÷ 3,6
• km/u = m/s × 3,6

All calculations are first converted to km/u for maximum accuracy.

Example

Input:

• Value: 100
• From: km/u
• To: mph

Result:

• 62,14 mph
