Speed Converter

Convert speed between m/s, km/h, mph, knots and ft/s.

Value

From

Converted value 62.137

Formula: result = value × (from in m/s) ÷ (to in m/s)

Step-by-step with your numbers:

1. Values used:

2. Value = 100

3. From = 0.2778

4. To = 0.447

6. Value x From = 100 x 0.2778 = 27.778

7. Converted value = (Value x From) / To = 27.778 / 0.447 = 62.137

Convert speeds between metric, imperial and nautical units.

The math behind it

Each unit is expressed in meters per second, then divided by the target unit. 1 mph = 0.44704 m/s.

100 km/h to mph → 100 × 0.277778 ÷ 0.44704 = 62.1 mph.

How fast is a knot?

1 knot = 1 nautical mile per hour ≈ 1.15 mph ≈ 1.852 km/h.
