Frequently asked questions
- When should I use km/h instead of mph?

- Can the result be negative?
- You normally enter the speed magnitude — negative usually means a typo unless you deliberately model direction separately.
- How precise is the result?
- Linear conversion with a fixed factor — exact apart from the decimals you type.
- What is the most common input mistake?
