Distance, Speed & Travel Time
Solve speed–distance–time relationships and estimate driving, walking, cycling, arrival and multi-stop journey durations from values you choose.
Calculate travel time, walking and cycling duration, coordinate distance, bearings, map scale, route segments and fuel stops with 12 transparent tools.

Calculate speed, distance or travel time from any two known values with clear unit conversions and step-by-step working.
Calculate driving time from trip distance, realistic average driving speed and planned stop minutes.
Estimate walking time from walking distance, average pace and optional rest minutes.
Calculate the great-circle distance between two latitude and longitude coordinates in kilometers, miles and nautical miles.
Calculate cycling time from ride distance, expected average cycling speed and planned break time.
Convert a measured map distance and map scale into real ground distance in metric and imperial units.
Calculate the initial true compass bearing between two latitude and longitude points with a cardinal direction.
Calculate arrival time from departure time, travel hours, travel minutes and planned stop time.
Calculate the great-circle midpoint between two latitude and longitude coordinates.
Calculate total journey time from route distance, average speed, number of stops and minutes per stop.
Add up to six route segment distances and calculate each segment’s share of the total route.
Estimate fuel stops from trip distance, vehicle fuel economy, tank capacity and reserve fuel.
This collection turns distances, average speeds, clock times, map scales and coordinate pairs into transparent planning estimates. Each page identifies its inputs, formula, units, rounding, limitations, primary references, colored result details and value-specific calculation steps.
Solve speed–distance–time relationships and estimate driving, walking, cycling, arrival and multi-stop journey durations from values you choose.
Calculate spherical great-circle distance, initial true bearing and geographic midpoint between latitude and longitude pairs.
Convert representative map scale, total separate route segments and estimate refueling stops using vehicle and trip assumptions.
