### How do you convert customary to metric?

There are exactly 2.54 centimeters in one inch. This is the basic fact that needs to be memorized for any of the distance conversions between metric and customary measurement. To convert from cm to inches, we divide the number of centimeters by 2.54 to get the result.

What is customary and metric system?

The metric system and the US customary system are identical in accuracy. The reason is very simple—the US customary system is defined in terms of not just the metric system in general but more specifically SI: 1 yd = 0.9144 m; 1 lb = 0.453 592 37 kg; 1 s = 1 s (The US customary system uses the SI time units);

Why doesn’t the US use the metric system?
