How to convert everyday measurements
Use these tools when arranging a call across time zones, comparing overseas prices, reading a rental listing or shopping for clothes. Calculators run in your browser; currency rates require an internet connection.
Common conversion formulas
| Conversion | Formula and example |
|---|---|
| Feet + inches to centimeters | (feet × 12 + inches) × 2.54; 5′8″ = 172.72 cm |
| Pounds to kilograms | lb × 0.45359237; 150 lb ≈ 68.04 kg |
| Square feet to square meters | sq ft × 0.09290304; 1,000 sq ft = 92.90304 m² |
| Fahrenheit to Celsius | (°F − 32) × 5 ÷ 9; 68 °F = 20 °C |
| Miles to kilometers | miles × 1.609344; 5 miles = 8.04672 km |
Does the time converter account for daylight saving?
Yes. Choose the source and destination cities and the date of your call. Their offsets are calculated for that date using your browser’s time zone data. A country can have multiple time zones, so choose the correct city. Recheck important appointments around daylight-saving clock changes.
Are exchange rates live trading prices?
No. The currency tool uses daily reference rates from Frankfurter. Check the date and status next to the result. Rates may be saved or unavailable; banks and cards can apply different rates and fees.
Is 5 feet 8 inches the same as 5.8 feet?
No. 5 feet 8 inches is 172.72 cm. Decimal 5.8 feet is 176.784 cm. Enter feet and inches in their separate fields.
Are shoe and pants sizes universal?
No. The shoe tool uses the linked ASICS adult size chart. Fit varies by brand and style. Pants W/L values are inch measurements: W32 L30 corresponds to 81.28 cm waist and 76.2 cm inseam; a garment’s actual fit can differ.
Which gallon should I choose?
A US liquid gallon is 3.785411784 liters; an imperial gallon is 4.54609 liters. Choose the unit used by the source label, rather than assuming both are equal.
