A certain food has a gluten ratio of 13 mg of gluten per L of the food. What is the gluten ratio in micrograms per milliliter uh

hammer [34]

For this case we must do a conversion. By definition we have to:

1 milligram equals 1000 micrograms

1 liter equals 1000 milliliters

So:

$13 \frac {mg} {L} * (\frac {1} {1000} * \frac {L} {mL}) * (\frac {1000} {1} * \frac {ug} {mg}) =\\\frac {13 * 1000} {1000} * \frac {ug} {mL} =\\13 \frac {ug} {mL}$

Answer:

$13 \frac {ug} {mL}$
