Velocity and Speed Formulas
Speed is defined as the rate at which an object covers distance:
$$\text{Speed} = \frac{\text{Distance}}{\text{Time}}$$
Conversion Factors
- $1\text{ km/h} \approx 0.621371\text{ mph} \approx 0.277778\text{ m/s} \approx 0.539957\text{ knots}$
- $1\text{ mph} \approx 1.609344\text{ km/h} \approx 0.44704\text{ m/s} \approx 0.868976\text{ knots}$
- $1\text{ knot} = 1\text{ nautical mile per hour} = 1.852\text{ km/h} \approx 1.150779\text{ mph}$
