Common mistakes to avoid
- Dividing when you should multiply. Because 1 millimeter = 0.003281 feet, the answer should be smaller than the number you started with.
- Rounding too early. Convert first at full precision, then round the final answer to the precision the task actually needs.
How precise does the answer need to be?
For everyday measurements round to the nearest whole unit or to one decimal place. Machining, sewing and construction usually need at least two decimals — and it is worth measuring in the target unit directly when tolerance matters.
