How many cups are there in 6.25*10^22 nl? hint: nl is the abbreviation for nanoliter.

A nano is essentially one-billionth or 1/1,000,000,000.
Since writing all these zeroes is inefficient and can easily lead into errors, we'll just use scientific notation instead.
A nanoliter is  liters.

So we have  liters.

A liter is 4.22675 cups. So now we can multiply 4.22675 by 6.25 * 10^13.
Use a calculator... you get 26.4171875 * 10^13.

*Note: There may be slight precision errors. This is inevitable when you're working with very large numbers, as the smallest initial change can spiral into much larger differences.
