Examining the figure, how many orders of magnitude larger is a person than a bacterial cell?

This question is repeated. I will copy the same answer provided by myself.

Well you did not show the figure, but I can show you how to do it.

Suppose the person is 6 feet tall and the bacteria cell is 1 micrometer in length.

So, put both magnitudes in the same units. I will use meter.

Person: 6 feet * 0.3048 m / foot = 1.8288 m, which in orders of magnitud is about 2 m

Bacteria cell: 1 micrometer * 1 m / 1,000,000 micrometer = 1 * 10 ^ -6 m.

Now divide: 2m / 10^ -6 m = 2,000,000

So a person is about 2 million times larger than a bacteria cell.

If the numbers in your figure are different you can use the same method to get a new result according to your figure.
