Units explained
Hand
A hand is an Imperial unit of length equal to 4 inches (101.6 mm). It is used primarily to measure the height of horses at the withers.
The hand derives from the average breadth of a human hand and was standardised at exactly 4 inches by the Statute of Henry VIII in 1541.
Hands are used worldwide for horse height specification (the typical riding horse is 14–17 hh). Also used in some equestrian-adjacent contexts. The unit is now almost exclusively a horse-measurement convention.
Standardised at 4 inches by Henry VIII in 1541; value became exact in 1959 when the inch was fixed at 25.4 mm.
Centimeter
A centimeter is a metric unit of length equal to one hundredth of a meter (1/100 m). It is one of the most commonly used SI sub-units in daily life, especially for measuring small objects, body dimensions, paper sizes, and short distances.
The centimeter emerged from the French metric system established by the French Academy of Sciences in 1793. The metric system introduced decimal-based prefixes (milli-, centi-, deci-, deca-, hecto-, kilo-) to create proportional sub-units of the meter.
Centimeters are the standard unit for everyday measurement in nearly every country outside the United States. They are used for body height, clothing sizes, rainfall, paper formats (A4 is 21 × 29.7 cm), screen dimensions, and most consumer product specifications.
Developed in France during the late 18th century as part of the metric system designed by the French Academy of Sciences. Formally adopted in France in 1795 and ratified internationally through the Metre Convention signed in Paris in 1875.

Step-by-step: convert hands to centimeters
- Write down the value in hands (hh).
- Multiply that value by the factor 10.16.
- The product is the equivalent value in centimeters (cm).
- To reverse, multiply the centimeter value by 0.0984251969.
Worked examples
Example 1 — Convert 1 hh to cm:
1 × 10.16 = 10.16 cm
Example 2 — Convert 100 hh to cm:
100 × 10.16 = 1016 cm
Real-world example — Pet and accessory dimensions
A 3-hand dog leash equals a tidy round value in centimeters. Pet-supply shopping frequently mixes the two units across product specifications.
3 hh × 10.16 = 30.48 cm
Real-world example — Fabric and tailoring
One hand of fabric converts to a value in centimeters commonly used for seam allowances. Garment patterns frequently switch between the two units on a single instruction sheet.
1 hh × 10.16 = 10.16 cm
Real-world example — Body height conversion (reverse direction)
You measure 1.75 hands tall and need to fill in a gym membership form or medical record that asks for height in centimeters. This is the most-used everyday length conversion in metric-using countries.
1.75 hh × 10.16 = 17.78 cm
