Speed Distance Time Calculator
Calculate speed, distance, or time when you know the other two. Essential for physics and travel planning.
Our Speed-Distance-Time Calculator solves for any of the three variables. Here's how to use it:
Step 1: Select what you want to calculate: speed, distance, or time.
Step 2: Enter the two known values with their units.
Step 3: Select your preferred output units.
Step 4: Click 'Calculate' to see the result.
The calculator also shows: - Conversions to alternative units - Formulas used - Real-world examples at similar speeds
The three fundamental motion formulas:
Speed = Distance / Time Distance = Speed × Time Time = Distance / Speed
Unit conversions: - 1 km/h = 0.621 mph = 0.278 m/s - 1 mph = 1.609 km/h = 0.447 m/s - 1 m/s = 3.6 km/h = 2.237 mph
Example: 100 km at 50 km/h: Time = 100 / 50 = 2 hours
