Calculation Principles & Formulas
This tool uses classical kinematics formulas to solve for the third variable given any two (Speed, Distance, Time). It automatically handles unit conversions between Metric and Imperial systems.
【Basic Formulas】
Distance = Speed × Time
Speed = Distance ÷ Time
Time = Distance ÷ Speed
【Unit Conversion Examples】
1 km/h ≈ 0.2778 m/s
1 mph ≈ 1.6093 km/h
Note: Calculations assume constant velocity. Real-world speeds may vary.
