Good to know
- Answers come back at six significant figures. 3.5 km lands on 2.1748 mi rather than a long decimal tail, which is the part of the number you would write down anyway.
- A year counts as 365 days. That is what the time category divides by, so a year converts to 52.1429 weeks rather than a leap-year-adjusted figure.
- The converted number is kept in R. Press
alphathenRto pull it into your next calculation instead of retyping it.
