Conversion Definitions
mph, miles per hour, measures how many miles an object travels in one hour in the imperial system. It is a common unit for vehicle speeds, especially in the United States and UK, reflecting the distance covered over time in miles.
kmh, kilometers per hour, indicates how many kilometers an object moves in one hour in metric units. Widely used outside the US, it provides a standard way to express speed in countries adopting the metric system, reflecting movement over kilometers per hour.
