50 μm = 5 × 10⁻⁵ m in diameter
<h3>Steps</h3>
1μm = 1 x m
<h3>Given</h3>
1μm = 1 x m
50μm = 50 x m
50μm = 50 x 10 x
50μm = 5 x m
<h3>Conclusion</h3>
A human hair is approximately 50 μm = 5 × 10⁻⁵ m in diameter
<h3>How big is a human hair on average?</h3>
between 17 and 181 micrometers
The typical diameter of human hair can range from 17 micrometers to 181 micrometers, according to research. Using 50 micrometers as an average figure for its diameter, this translates to 50,000 nanometers.
<h3>What is a human hair's diameter in inches?</h3>
The finest hair is flaxen, with a diameter ranging from 1/1500 to 1/500 of an inch. the coarsest hair is black, measuring between 1/450 and 1/140 of an inch.
