FAQ

Why do car specs use kph and mph?

Vehicle information is published for different markets, so the same speed may appear in either metric or imperial units.

Should I use the rounded answer?

Use a rounded answer for quick reading, but keep the exact value when the number affects a record, purchase, recipe, schedule or specification.

Why include nearby conversion links?

Nearby links make it easy to compare similar values without typing a new query, which is useful when the first number was only an estimate.
