Frequently Asked Questions
How many mL is 800 mg?
800 mg equals 0.8 mL for water (density 1 g/mL). For other substances, divide by the substance density: mL = mg ÷ (density × 1,000).
How do I convert 800 mg to mL?
Use the formula mL = mg ÷ (density × 1,000). For water with density 1 g/mL: 800 ÷ 1,000 = 0.8 mL.
Is 800 mg the same as 0.8 mL?
Only for water and substances with density 1 g/mL. For ethanol (density 0.789), 800 mg ≈ 1.013942 mL. For olive oil (density 0.92), 800 mg ≈ 0.869565 mL.
