Travel Converter
Convert distance, speed, and temperature for travel
Convert stated trip quantities in their matching tools: speed, distance, temperature and fuel consumption need different units and assumptions.

Context
A speed includes time, so km/h-to-mph belongs in the speed calculator; km-to-miles belongs in the distance calculator. Temperature scales require an offset. For fuel estimates, name the gallon convention and keep the original measurement or rating conditions. A unit conversion alone cannot establish trip time, weather comfort or actual consumption.
For the distance examples here, a mile means the international mile of 1609.344 m, as given by NIST revised factors. The length measurement workflow distinguishes that mile from the fixed 1852 m international nautical mile.

Why this matters
Convert a stated speed
For a hypothetical 90 km/h value, use km/h-to-mph rather than a distance converter. The result is approximately 55.9234 mph.
Re-express a forecast value
A stated 18°C is 64.4°F. The numerical conversion does not decide clothing needs or weather conditions beyond that value.
Understanding fuel economy and costs
For a hypothetical 30 US MPG consumption, convert to approximately 7.8405 L/100km before estimating liters over a stated trip distance. Keep rating conditions separate from actual trip consumption.
Compare a trip distance
A hypothetical 500 km trip is approximately 310.6856 miles. Elapsed time requires an independently stated average speed and any stops.
Frequently asked
The speed limit is 100 km/h but my car shows mph. What's the speed limit in mph? →
100 km/h is approximately 62.1371 mph. Use km/h to mph for speed, and km to miles for distance. This conversion makes no claim about a jurisdiction’s speed limits.
How do I express a stated 15°C in Fahrenheit? →
15°C × 9/5 + 32 = 59°F. Use Celsius to Fahrenheit. The conversion does not establish clothing needs or other weather conditions.
How far is 50 kilometers in miles? →
50 km is approximately 31.0686 miles. Use km to miles for distance. At an assumed constant 60 mph with no stops, the ideal time is about 31.1 minutes; actual travel time requires actual speed and stop information.
My home car gets 28 mpg. How does that compare to a European car rated at 6.5 liters per 100 km? →
28 US MPG is approximately 8.4005 L/100km. A hypothetical 6.5 L/100km value is numerically lower, but different test ratings do not establish actual trip consumption. Use the fuel calculator with a named gallon convention and retain source context.
Gas costs €1.50 per liter. How much is that per gallon? →
At a hypothetical €1.50/L, one US liquid gallon costs €1.50 × 3.785411784 ≈ €5.6781; one Imperial gallon costs €1.50 × 4.54609 ≈ €6.8191. These are the same stated price expressed per different volumes, not a current price or exchange-rate comparison. See volume units.
I'm flying into a city at 2000 meters elevation. How many feet is that? →
A stated 2000 m is approximately 6561.6798 ft using the international foot. Use meters to feet. This conversion gives no medical or operational flight advice.
Where can I verify these conversion definitions? →
The worked numbers derive from NIST named conversion factors, NIST exact-pound footnote 22, NIST temperature formulas and NIST Handbook 44 Appendix C. Fuel rating context is described in the EPA testing explanation. Hypothetical examples state their own assumptions.
