Ahuman hair is approximately 50 um in diameter. express this diameter in meters.

A human hair is approximately 50 μm = 5 × 10⁻⁵ m  in diameter

Some units of length and its conversion that need to be recalled are:

Let us now tackle the problem !

Given:

A human hair is approximately 50 μm in diameter.

A human hair is approximately 50 μm = 5 × 10⁻⁵ m  in diameter

Grade: High School

The approximate diameter of a human hair expressed un meter is 0.000005m

The micrometer is a term of Greek origin that refers to a unit of length equivalent to one thousandth of a millimeter. A micrometer is represented by the symbol µm.

To begin, it is necessary to take into account that:

To express 50µm in meters, the following mathematical formula must be used.

Then the Х must be replaced with the number of micrometers, that is 50µm and perform the mathematical operation as shown below.

According to the above, the correct answer is 0.000005m
