Unit Converter — Frequently Asked Questions

Is a nautical mile the same as a regular mile?+

No. A nautical mile = 1.852 km (1.151 regular miles). It's based on one minute of latitude and is used in maritime and aviation navigation.

Why are there two 'ton' units?+

A metric ton (tonne) = 1000 kg. A US (short) ton = 907.18 kg (2000 lbs). A UK (long) ton = 1016.05 kg (2240 lbs). Always clarify which ton is meant.

Is 1 GB exactly 1000 MB or 1024 MB?+

In SI (decimal): 1 GB = 1000 MB. In binary (IEC): 1 GiB = 1024 MiB. Storage manufacturers use decimal (smaller), while OS often reports binary (larger), causing confusion about 'missing' space.
