### Conversion

How would you convert something like -4.09 x 10^-19 into nanometers?

Glad you figured out your mistake! For the future though, I like to use dimensional analysis for my conversions as to avoid any mistakes or confusion. I use the following set up. Let's say I'm trying to convert from meters to nanometers, and I have $4.7\times 10^{-7}$ meters. I know that 1 nanometer is 10^-9. So, I can set up my conversion as seen below, and that will give me my answer in nanometers!

$4.7 \times 10^{-7} m \times \frac{1 nm}{1 \times 10^{-9} m}$

Hope this helped!
