Road Trip Time Calculator

How it is calculated

Driving time is distance ÷ average speed in hours. Stop time is number of stops × minutes per stop ÷ 60 hours. The total is driving time plus stop time. Each result is displayed as hours and minutes, with minutes rounded to the nearest whole minute. Distance and speed must use matching units, such as kilometers and km/h or miles and mph, and the tool does not convert between them. Speed must be greater than zero, and distance, stops and minutes per stop cannot be negative. If you leave the stops or minutes fields empty, they are treated as zero, so the total then equals the driving time. The tool uses one constant average speed; it does not model traffic, slower roads or hours-of-service rules.

Common mistakes

• Using the speed limit as the average speed. Towns, junctions, fuel and traffic bring the real average well below the limit.
• Mixing units, such as distance in miles with speed in km/h. The tool gives a wrong answer without any warning.
• Entering the total stop time in the minutes-per-stop field. That field is per stop, so 3 stops of 20 minutes is 3 and 20, not 60.
• Forgetting overnight rests on a long trip. The result is continuous elapsed time and does not include sleep or hotel nights.
• Reading 5h 38m as 5.38 hours. The part after the h is minutes, so 5h 38m is 5.63 hours.
