i would use inches
To measure your arm length, stand up straight with your arms relaxed at your sides. Use a measuring tape and extend it from the top of your shoulder (where it meets your neck) down to your wrist bone. Make sure your arm is straight when measuring for accuracy. Alternatively, you can measure from your shoulder to your fingertips for a longer measurement.

The length of one arm is about 40% of your height
The length of an individual's arm span is generally about equal to their height. To measure it, one can extend both arms fully to the sides and measure the distance from fingertip to fingertip. Typically, this measurement can provide insights into body proportions and is sometimes used in various fields, such as sports and medicine. However, individual arm spans can vary based on factors like genetics and body composition.
Mechanical advantage= effort arm length/ load arm length For Example Effort arm=120 cm Load arm length= 40 cm MA-120/40 = 3
A ruler
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 measure crank arm length accurately, use a ruler or measuring tape to measure the distance from the center of the bottom bracket to the center of the pedal spindle. This measurement will give you the crank arm length.
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.
A foot is a unit of distance about the length from your wrist to your elbow. Anything you can measure can be expressed in feet. If it is smaller than your arm or longer than a portion of a mile then I would probably choose a different measurement.

An ell is an obsolete unit of measurement - the length of an arm from elbow to tip of the middle finger.
umm well maby you get a ruler and put it up to your arm, then u rite down what the number is
The mechanical advantage of a lever is calculated by dividing the length of the input arm by the length of the output arm. In this case, the mechanical advantage would be 3/2, which simplifies to 1.5. This means that for every 1 unit of effort applied to the input arm, the lever can lift 1.5 units on the output arm.
The best method to accurately measure crank arm length is to use a ruler or measuring tape to measure the distance from the center of the bottom bracket to the center of the pedal spindle. This measurement should be taken in millimeters for precision.
