Common Mistakes to Avoid
Rounding centimeters too aggressively
Solution:
1 inch is exactly 2.54 cm — rounding to 2.5 introduces a small but compounding error over larger measurements.
Confusing inches with feet
Solution:
12 inches = 1 foot — double-check which unit a measurement is actually given in before converting.
Mixing metric and imperial mid-calculation
Solution:
Convert fully to one system before doing further math, rather than combining inches and centimeters in the same equation.
