Enter milligrams or cups into the calculator to convert between mass and volume using ingredient density.
Mg to Cups Formula
The following formula converts milligrams to cups using ingredient density; use 236.588 mL for US cups or 250 mL for metric cups.
\mathrm{cups_{US}} = \frac{m_{\mathrm{mg}}}{1000\,\rho \cdot 236.588} \quad\quad
\mathrm{cups_{metric}} = \frac{m_{\mathrm{mg}}}{1000\,\rho \cdot 250}- US cup = 236.588 mL
- Metric cup = 250 mL
- 1 g = 1000 mg
- ρ = density in g/mL (e.g., water = 1.000 g/mL; honey ≈ 1.438 g/mL).
- Heavier (denser) ingredients yield fewer cups for the same mass.

How do you convert milligrams to cups? Convert mg to grams (÷1000), compute mL by dividing grams by density (g/mL), then convert to cups by dividing mL by the cup size (236.588 for US, 250 for metric).
How do you convert cups to milligrams? Multiply cups by the cup size in mL, multiply by density to get grams, then convert grams to mg (×1000).
Example Problem
Convert 75,000 mg of honey to US cups.
Use the formula: cups = (mg ÷ 1000) ÷ (ρ × 236.588); with ρ = 1.438 g/mL for honey.
cups = (75,000 ÷ 1000) ÷ (1.438 × 236.588) ≈ 0.2205 cups
