Frequently Asked Questions
How many mL is 100 mg?
100 mg equals 0.1 mL for water (density 1 g/mL). For other substances, divide by the substance density: mL = mg ÷ (density × 1,000).
How do I convert 100 mg to mL?
Use the formula mL = mg ÷ (density × 1,000). For water with density 1 g/mL: 100 ÷ 1,000 = 0.1 mL.
Is 100 mg the same as 0.1 mL?
Only for water and substances with density 1 g/mL. For ethanol (density 0.789), 100 mg ≈ 0.126743 mL. For olive oil (density 0.92), 100 mg ≈ 0.108696 mL.
