Mistakes to avoid with length conversions
- Mixing unit systems mid-calculation — convert everything first, then do the math.
- Treating yards and meters as equal: a yard is ~8.6% shorter, which compounds over long distances.
- Rounding centimeters to inches too early when cutting materials — keep one extra decimal until the final cut.
