About Converting Hands to Inches
Hand and Inch both measure length. Specifically: A hand is four inches, often used for horse height, and an inch is exactly 0.0254 meters.
Formula
inches = hands × 4
This factor comes from each unit's defined relationship to the category's base unit: 1 hand equals 0.1016 base units, and 1 inch equals 0.0254 base units, so dividing one by the other gives the direct hand-to-inch factor of 4.
Simple example
1 hh × 4 = 4 in
1 hand = 4 inches.
Real-world example
10 hh × 4 = 40 in
10 hands = 40 inches.
