Mistakes to avoid

Dropping the units

A bare number without a unit is easy to misread later. Always write the unit with the result.

Mixing similar-sounding units

US and imperial gallons, pints and tons are different sizes, and decimal kilobytes differ from binary kibibytes.

Multiplying when you should divide

Converting to a smaller unit gives a bigger number, and converting to a larger unit gives a smaller one. If your answer moves the wrong way, you have inverted the factor.

Background

A conversion table is handy for common values, but a calculator is faster and avoids interpolation errors for anything in between.

Writing the units next to every number while you work is the simplest way to avoid mistakes. If the units do not cancel to leave the one you want, the calculation is set up wrongly.

Singapore adopted the metric system in the 1970s, replacing imperial units and traditional Chinese measures in most official uses. Metric units are now standard in schools, trade and government, but older units survive in property, markets and imported goods.
