A familiar situation
Prüfen Sie Fahr-, Lauf- oder Reisegeschwindigkeiten anhand von Distanz und Dauer.
How to use this calculator
- Enter distance, elapsed time.
- Select Calculate to see the answer and its breakdown.
- Keep a scenario, change an input and compare the results.
Use consistent units and check the assumptions below before applying the result.
How speed is calculated
Calculate average speed from distance and elapsed time and convert between common speed units. Average speed uses total distance divided by total duration; it differs from average velocity when direction and displacement matter. A 150 km trip taking 2 hours averages 75 km/h. The calculation validates each input and keeps its stated units explicit. Include all elapsed time for trip-average speed or exclude stops for moving speed. This is an estimate for the stated assumptions; confirm measurements and any applicable professional or local standards before relying on it.
average speed = distance ÷ elapsed timeA 150 km trip taking 2 hours averages 75 km/h.
Assumptions & useful context
The result depends on the values you enter and the method described above. Displayed numbers may be rounded; calculations use the unrounded values. Check that this model matches your situation before relying on it.
Frequently asked questions
Does it include stops?
Include all elapsed time for trip-average speed or exclude stops for moving speed.
Can speed be negative?
Speed is a nonnegative magnitude; direction belongs to velocity.
