Ahuman hair is approximately 56 µm in diameter.
express this diameter in meters.
answer in units of m

The diameter is 0.000056 m

Explanation:

Lets explain the relation between the meter and the micrometer

1 Meter is equal to 1000000 (one million) micrometers

1 micrometer =

The symbol of the meter is m

The symbol of micrometer is μm

A human hair is approximately 56 µm in diameter

We need to express this diameter in meter

To do that we divide this number by 1,000,000 or multiply it by

→  56 µm = 0.000056 m

→ OR

→

→ 56 µm = 0.000056 m

The diameter is 0.000056 m
