Frequently Asked Questions
How many mL is 500 mg?
500 mg equals 0.5 mL for water (density 1 g/mL). For other substances, divide by the substance density: mL = mg ÷ (density × 1,000).
How do I convert 500 mg to mL?
Use the formula mL = mg ÷ (density × 1,000). For water with density 1 g/mL: 500 ÷ 1,000 = 0.5 mL.
Is 500 mg the same as 0.5 mL?
Only for water and substances with density 1 g/mL. For ethanol (density 0.789), 500 mg ≈ 0.633714 mL. For olive oil (density 0.92), 500 mg ≈ 0.543478 mL.
