1 L = 1000 mL

For example, if you have 500 mL and want to convert it to liters, the calculation would be:

500 mL / 1000 mL/L = 0.5 L

3. Weight calculations:

To convert milligrams to grams, use the following formula:

1 g = 1000 mg

For example, if you have 250 mg and want to convert it to grams, the calculation would be:

250 mg / 1000 mg/g = 0.25 g

4. Dilution calculations:

To calculate a dilution ratio, use the following formula:

(Weight in mg / Concentration in mg/mL) = Volume in mL

For example, if you have 100 mg of medication and want to dilute it to a 1:100 ratio, the calculation would be:

(100 mg / 1 mg/mL) = 100 mL
