About Converting Hands to Zettameters
Hand and Zettameter both measure length. Specifically: A hand is four inches, often used for horse height, and zettameter is 1e+21 meter units.
Formula
zettameters = hands × 1.016e-22
This factor comes from each unit's defined relationship to the category's base unit: 1 hand equals 0.1016 base units, and 1 zettameter equals 1e+21 base units, so dividing one by the other gives the direct hand-to-zettameter factor of 1.016e-22.
Simple example
1 hh × 1.016e-22 = 1.016e-22 Zm
1 hand = 1.016e-22 zettameters.
Real-world example
10 hh × 1.016e-22 = 1.016e-21 Zm
10 hands = 1.016e-21 zettameters.
