**1 μm = 9.8425196850394E-6 hh**

One micrometer equals approximately 9.843 x 10-6 hands. A hand (101,600 um) contains about 101,600 micrometers. The micrometer measures biological structures of horses; the hand measures the horses themselves.

## Units

### Micrometer (μm)

One millionth of a meter, also called a micron. Used in biology for cell sizes, in engineering for surface finishes, and in manufacturing tolerances.

### Hand (hh)

Exactly 4 inches (10.16 cm). The standard unit for measuring the height of horses, measured from the ground to the withers.

## Background

A hand is 101,600 um. A horse hair (150 um) is 0.00148 hands wide. A horse red blood cell (5.5 um) is 0.0000541 hands. The veterinary world uses both units: micrometers for pathology slides, hands for the animal on the examination table.

## Good to Know

A veterinarian examining a horse works at both scales simultaneously. The horse stands 16 hands tall (macro). Its blood smear shows 5.5 um red blood cells (micro). Same animal, same veterinarian, two units separated by a factor of 100,000. Veterinary medicine spans 5 orders of magnitude in one patient.

## FAQ

### How many hands is 1 micrometer?

One micrometer equals approximately 9.843 x 10-6 hands (about 10 millionths of a hand).

### How many micrometers are in 1 hand?

One hand contains exactly 101,600 micrometers.

### When is this conversion used?

In equine veterinary science where horse height (hands) and tissue samples (micrometers) describe the same animal at different scales.

## Non-Frequently Asked Questions

### How many horse cells make up 1 hand of height?

An average horse cell is about 20 um. One hand (101,600 um) is about 5,080 cells tall. A 16-hand horse is about 81,280 cells from hoof to withers. That is a lot of cells behaving cooperatively to make one horse.

### Is a hand literally a hand in micrometers?

Your palm is about 80,000-100,000 um (80-100 mm) wide. A horse-measurement hand is 101,600 um. So yes, a 'hand' is almost exactly the width of an adult human palm in micrometers. The unit lives up to its name at every scale.

### How thick is a horse's skin in hands?

Horse skin varies from 1-5 mm (1,000-5,000 um) depending on location. That is 0.01-0.05 hands. So a horse's skin is about 1-5% of a hand thick. The measuring unit is thicker than the skin of the animal it measures. Meta-measurement.
