Traveling internationally means navigating different measurement systems. From reading road signs to understanding weather forecasts, this guide covers all the essential conversions you need.
Quick Travel Converters:
Distance and Road Signs
Most countries use kilometers for road distances, while the US uses miles. Understanding this conversion is crucial for trip planning and following speed limits.
Key Distance Conversions
- 1 kilometer (km) = 0.62 miles (mi)
- 1 mile = 1.61 kilometers
- 100 km ≈ 62 miles (easy to remember!)
- 80 km/h ≈ 50 mph (common speed limit)
Quick mental math: To convert km to miles, multiply by 0.6. To convert miles to km, multiply by 1.5 (or use our distance converter).
Weather and Temperature
Understanding weather forecasts is essential for packing and planning activities. Most of the world uses Celsius, but if you're from the US, you're used to Fahrenheit.
Temperature Quick Reference
| °C | °F | What to Wear |
|---|---|---|
| -10°C | 14°F | Heavy winter coat, gloves |
| 0°C | 32°F | Freezing - winter jacket |
| 10°C | 50°F | Light jacket or sweater |
| 20°C | 68°F | Perfect - t-shirt weather |
| 30°C | 86°F | Hot - shorts and sunscreen |

Luggage Weight Limits
Airlines use different weight systems depending on the country. Most international airlines use kilograms, while US domestic flights use pounds.
Common Luggage Weights
- 23 kg = 50 lbs (standard checked bag limit)
- 32 kg = 70 lbs (heavy bag surcharge starts)
- 7-10 kg = 15-22 lbs (typical carry-on limit)

Fuel and Gas
Fuel prices vary dramatically by country, and they're measured differently too. Europe uses liters, the US uses gallons.
Fuel Conversions
- 1 US gallon = 3.78 liters
- 1 liter = 0.26 gallons
- €1.50/liter ≈ $5.67/gallon (when €1 = $1)
Rental car tip: If you see fuel at €1.80/liter, that's about $6.80/gallon - helpful to know before renting!
Height and Personal Measurements
You might need to provide your height and weight for activities like skydiving, zip-lining, or medical forms.
Common Height Conversions
| Feet & Inches | Centimeters |
|---|---|
