A certain food has a gluten ratio of 13 mg of gluten per L of the food.

Question

What is the gluten ratio in micrograms per milliliter hg/mL?

Answer 1

To convert from milligrams to micrograms, you multiply by 1000.
So, 13 mg = 13,000 micrograms
To convert from liters to milliliters, you multiply by 1000.
So, 1 L = 1000 mL

Therefore, the gluten ratio is:
13,000 micrograms / 1000 mL = 13 micrograms per milliliter (µg/mL)
