About how much is 1.4 mL/kg?

Question

i need a picture of something that's that size

Answer 1

if you are converting a volume (mL) to a mass (Kg), then it would be 0.0014kg.

if you just want to divide the answer, 1.4 milliliters to every one kilogram

typically when you have a concentration it is first the weight per volume eg. mg/L or g/L.
