Question

A human hair is approximately 56 µm in diameter.

Express this diameter in meters.
Answer in units of m

Answer 1

The diameter is 0.000056 m

Step-by-step explanation:

Lets explain the relation between the meter and the micrometer

1 Meter is equal to 1000000 (one million) micrometers

1 micrometer =
`(1)/(1000000)=(1)/(10^(6))=10^(-6)`

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
`10^(-6)`

→
`(56)/(1000000)=0.000056` 56 µm = 0.000056 m

→ OR

→
`56*10^(-6)=0.000056`

→ 56 µm = 0.000056 m

The diameter is 0.000056 m
