54 hair-width’s of change

In my life time, that’s how much the radius of the earth has changed, according to NASA.

The scientists estimated the average change in Earth’s radius to be 0.004 inches (0.1 millimeters) per year, or about the thickness of a human hair, a rate considered statistically insignificant.

I am sure you were waiting with bated breath for that bit of news!

I’m just wondering if that means 108 hair-widths for the diameter??
