Calculate speed, distance, or time. Perfect for travel planning, fitness tracking, and physics problems.
Formula:
Distance = Speed × Time
Speed = Distance / Time
Time = Distance / Speed
Speed = Distance / Time. This is the fundamental formula used to calculate how fast something is moving over a distance in a given time period.
Use Time = Distance / Speed. For example, if you travel 100 km at 50 km/h, your travel time is 100/50 = 2 hours.
Speed is how fast you're moving, while velocity includes direction. In this calculator, we calculate speed (a scalar quantity).
