Mistakes to avoid

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.

Dropping the units

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

Forgetting squared and cubed units

Area and volume factors are the length factor squared or cubed, so 1 m² is about 10.76 sq ft, not 3.28.

Background

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.

Many conversion factors are exact by definition. The inch has been defined as exactly 2.54 centimetres since 1959, and the pound as exactly 0.45359237 kilograms, so conversions involving them can be as precise as you need.

For everyday use, three or four significant figures are usually enough. Engineering, science and trade documents may need more, and rounding should happen only at the end of a calculation.
