Which term refers to a non-SI unit of measurement used for horse height?

• A. Stallion
• B. Mare
• C. Filly
• D. Hand

Answer: (D)

Measuring a horse’s height uses a hand, a traditional unit equal to four inches. It’s a non-SI unit and remains standard in the horse world for expressing height at the withers. For example, a horse described as 15 hands tall is 60 inches tall at the withers. The other terms refer to the horse’s sex or age—stallion is an adult male, mare is an adult female, and filly is a young female—so they describe classifications rather than a unit of measure.
