You would use a measuring tape, with measurements in centimetres.

Well, honey, you'd want to use good ol' centimeters to measure the length of your arm. It's precise enough to give you an accurate measurement without getting all tangled up in those pesky decimals. So grab a ruler and start measuring, darling!

To calculate the moment arm in a mechanical system, you measure the perpendicular distance from the pivot point to the line of action of the force applied. This distance is important in determining the torque or rotational force in the system.
The metric system was created to standardize measurements. In the past, measurements were based on abstract things like the size of an arm or the width of a horse. When these became subunits for each other, it got complicated. So the metric system bases everything on divisions of 100. It helped scientific research because (hopefully) everyone, everywhere uses it and different countries don't have to convert everything.
In the NFL, arm length is measured from the tip of the shoulder to the tip of the longest finger while the arm is fully extended. This measurement is typically taken with the player standing upright and their arm outstretched to ensure accuracy. It is an important metric for evaluating quarterbacks and receivers, as it can impact their throwing ability and reach during gameplay.
Arm span is a measure of the arm

You can measure the length of your arm in centimeters or millimeters. To convert this measurement to meters, you would divide by 1000 for millimeters or 100 for centimeters. The other units like decimeters, kilometers, and decameters are not typically used for measuring the length of a human arm.
