Conversion Formula:
| From: | To: |
The conversion from milliliters (mL) to milligrams (mg) depends on the density of the substance. Since 1 mL of water has a mass of approximately 1000 mg, this conversion requires knowing the density of the specific substance being measured.
The calculator uses the conversion formula:
Where:
Explanation: The formula converts volume (1 mL) to mass (mg) using the substance's density, accounting for the fact that different substances have different mass per unit volume.
Details: Density is a critical factor in volume-to-mass conversions because different substances have different densities. For accurate conversions, you must know the exact density of the specific substance at the given temperature and pressure conditions.
Tips: Enter the density of your substance in g/mL. Make sure to use the correct density value for your specific substance and conditions, as density can vary with temperature and purity.
Q1: Why can't I convert mL to mg without knowing density?
A: Because mL measures volume while mg measures mass. The relationship between them depends on the substance's density, which varies between materials.
Q2: What's the density of water?
A: Pure water has a density of approximately 1 g/mL at 4°C, which means 1 mL of water equals 1000 mg.
Q3: How does temperature affect density?
A: Most substances expand when heated, decreasing their density. For precise conversions, use density values at the actual temperature of measurement.
Q4: Can I use this for any substance?
A: Yes, as long as you know the correct density value for that specific substance under your measurement conditions.
Q5: Why multiply by 1000?
A: Because 1 gram = 1000 milligrams, and density is typically given in g/mL, so we need to convert from grams to milligrams.
