Milligrams to Milliliters Calculator
Convert weight to volume for different solutions
Converting from weight (milligrams) to volume (milliliters) requires knowing the density of the solution. The relationship is:
Volume (mL) = Weight (mg) ÷ (Density (g/mL) × 1000)
The density factor of 1000 is needed because we're converting from milligrams (mg) to grams (g) in the calculation.
Common solution densities at room temperature (20°C):
- Water: 1.000 g/mL
- Saline Solution: 1.005 g/mL
- Glucose Solution: 1.016 g/mL
- Ethanol Solution: 0.789 g/mL
- Glycerin Solution: 1.261 g/mL
- Hydrogen Peroxide: 1.450 g/mL
- Acetic Acid: 1.045 g/mL
- Sodium Hydroxide: 1.525 g/mL
- Hydrochloric Acid: 1.184 g/mL
- Sulfuric Acid: 1.830 g/mL
Note: These densities are approximate and may vary with temperature and concentration.
Related volume conversions:
Microliters (µL) = Milliliters × 1000
Centiliters (cL) = Milliliters ÷ 10
Liters (L) = Milliliters ÷ 1000
These relationships help you work with volumes at different scales, from very small (microliters) to larger volumes (liters).
This conversion is essential in many fields:
- Pharmaceutical formulation and dosing
- Laboratory solution preparation
- Chemical process calculations
- Quality control testing
- Research and development
- Clinical laboratory procedures
- Industrial process control
Why do I need to know the solution type?
Different solutions have different densities, which affects the volume they occupy for a given weight. For accurate conversion, you need to know what type of solution you're working with.
How does temperature affect the conversion?
Temperature can affect a solution's density, which in turn affects the volume. Our calculator uses densities at room temperature (20°C). For very precise measurements or different temperatures, consult specific density tables or measure directly.
