Why 100 cm Is a Useful Benchmark

100 centimeters is exactly 1 meter — one of the cleanest metric-to-metric conversions there is. That also makes it a handy anchor point: since 1 meter ≈ 39.37 inches, and a yard is exactly 36 inches, a meter is just over 3 inches longer than a yard. Once you have that single fact memorized, you can estimate almost any other centimeter value by scaling up or down from it.
