1 cm ≈ 0.394 inches — divide cm by 2.54 for a precise inch conversion.
Your little finger is about 1 cm wide at the nail — useful when no ruler is nearby.
100 cm = 1 metre exactly. Always convert to metres for architectural plans.

Avoid these

Confusing linear cm with square cm. 21 cm of ribbon is not the same as 21 cm² of fabric.
Using 2.5 instead of 2.54 for inch conversion — the 1.6% error grows on long measurements.
Reading a clothing size label as cm when it is actually an EU size code (e.g. size 42 ≠ 42 cm).
