How do you convert g per mL to L?

Answer 1

This is a chemistry and nursing question.

If a solution is given in grams per ml, multiply by 1000 to get grams per liter.

For example, 0.0025 g / mL converts to 2.5 g / L.

Now, a question for you, the reader: Why would anyone express something in grams per milliliter, when a milliliter of water weighs almost exactly one gram? Where might this exact problem come up in real life?

Answer 2

Take the amount in grams and multiply this by the "g per L" value.

* * * * *

That is patently incorrect as basic dimensional analysis shows:

g has dimension [M]

g per L has dimensions [ML-3]

and your target, L. has dimensions [L3].

Multiply them together and you get a measure with dimension [M2L-3]. Not the dimensions of the required measure.

However, divide the amount in grams by the "g per L" value and you get

[M]/[ML-3] = 1/[L-3] = [L3].

Sadly, dimensional analyses is rather an overlooked aspect of mathematics.

Answer 3

To convert g/mL to L, divide the value in grams by 1000. For example, if you have 5 g/mL, you would divide 5 by 1000 to get 0.005 g/mL, which is the equivalent value in L.
