Frequently Asked Questions
How many mL is 840 mg?
840 mg equals 0.84 mL for water (density 1 g/mL). For other substances, divide by the substance density: mL = mg ÷ (density × 1,000).
How do I convert 840 mg to mL?
Use the formula mL = mg ÷ (density × 1,000). For water with density 1 g/mL: 840 ÷ 1,000 = 0.84 mL.
Is 840 mg the same as 0.84 mL?
Only for water and substances with density 1 g/mL. For ethanol (density 0.789), 840 mg ≈ 1.064639 mL. For olive oil (density 0.92), 840 mg ≈ 0.913043 mL.
