Formula
Speed Conversion Formula: 1. Speed in m/s = Input Value × Source Unit Factor (m/s) 2. Converted Speed = Speed in m/s / Target Unit Factor (m/s)
Definitions and limits
One knot is 1,852 m per hour. Mach is a ratio to local sound speed; this converter assumes approximately 340.29 m/s in dry air at 15 °C, not a universal constant.
Displayed values are rounded. Calculations use the full stored factors.
