How to convert speed
Enter a speed and select the source and target units. The converter supports road, aviation, marine, and physics-friendly speed units.
Speed uses meters per second as the base unit: result = amount x source factor / target factor.

Formula model
Base-unit conversion
Kilometers per hour, miles per hour, knots, and feet per second use standard definitions.
base = amount * factor + offset
result = (base - targetOffset) / targetFactor
result = (base - targetOffset) / targetFactor
Scope
Fixed conversions first
Currency, crypto, and market-rate conversions need live exchange data, so they are kept separate from the fixed scientific units in this build.
Exact units
Lengths, masses, storage, time, and most derived units.
Offset units
Celsius, Fahrenheit, and Kelvin conversions.
FAQ
