Frequently asked questions
How do I convert Fahrenheit to Celsius?
Celsius = (Fahrenheit − 32) × 5 ÷ 9. So 100°F is about 37.8°C, and 32°F is exactly 0°C.
How many GB are in a TB?
1,000 GB in decimal (SI) terms, or 1,024 GB in binary terms. Drive makers use decimal while operating systems usually use binary, which is why a 1 TB drive shows as roughly 931 GB.
How long is a mile in kilometres?
One mile is about 1.609 km, and one inch is exactly 2.54 cm.
Do the converters work offline?
Yes, apart from the currency converter, which needs a connection for live rates. Everything else is pure arithmetic in the browser.
