In weight and balance practice, which unit is commonly used to express the CG location along the datum?

The distance of the center of gravity along the datum is described as a distance from the reference point, called the arm. In weight and balance work, that arm is almost always expressed in inches. The CG location is found by taking the total moment (weight times its arm) and dividing by the total weight, giving a CG distance in inches from the datum. For example, if the total weight is 4,000 lb and the total moment is 32,000 lb-in, the CG location is 32,000 ÷ 4,000 = 8 inches from the datum. Feet, centimeters, or meters aren’t used for the arm in standard practice, because inches align with typical aircraft drawings and moment calculations (moment is in pound-inches).
