Conversion tricks and mini tools
Top 10 travel conversion cheatsheet
This cheatsheet lists ten travel conversions you can pre-save as bookmarks: temperature comfort bands, distance, speed, luggage weight, fuel volume, and currency sanity checks.
Store one canonical bookmark per pair you actually use—ten rarely opened links are worse than three trusted ones.
Key takeaways
- Memorize jacket/umbrella anchors in both °C and °F for your destinations.
- Walking ETAs: convert distance with your pace, not generic defaults.
- Know liters ↔ US gallons for rental fuel stops.
- Duty-free fl oz bottles: convert to ml before security limits.
How to convert
60 mph = 96.560563 km/h
Temperature comfort bands
Memorize a few anchors in both °C and °F for “light jacket” and “heavy coat” to reduce app toggling.
Distance and walking time
Convert km ↔ miles for walking ETAs using your personal pace, not generic defaults.
Driving speed limits
Convert posted limits mentally with a safe margin; remember km/h vs mph sign colors differ by country.
Fuel and rental car math
Know liters ↔ US gallons for refueling stops and per-tank range estimates.
Jet lag and hydration numbers
Convert fluid ounces to milliliters when reading US hydration advice abroad.
Bookmark discipline
Store one converter page per pair you actually use; avoid a folder of ten rarely opened links.
Altitude and boiling point
Water boils below 100 °C at elevation—convert recipes that assume sea-level simmer times when hiking or in mountain towns.
Airport liquid rules
Security limits are often per container in milliliters; convert fl oz from duty-free purchases before the security line.
Tipping and rounding
Some countries round cash to the nearest five; convert tip percentages on the pre-tax subtotal the local way, not yours.
