Question

If a flea weights 0.103 cg what is it’s weight in nanograms?

Answer 1

The flea weighs 1030000 nanograms.

Explanation:

To understand how to apply this conversion, you have to understand their magnitude in comparison to a gram.

A centigram is `1 *10^-2` grams, whereas a nanogram is `1*10^-9`grams. If you divide a centigram by a nanogram, you get the number of nanograms in one centigram and the conversion factor. You can do this because you converted both into the same units: grams.

`(1*10^-2)/(1*10^-9)` equals `1*10^7` so there are `1*10^7` nanograms in one centigram.

To find the number of nanograms in a certain amount of centigrams, you multiple the amount of centigrams by `1*10^7`.

Hence, .103cg equals 1030000 ng because `.103*(1*10^7)` equals 1030000.
