grams to milliliters calculator

How this grams to milliliters calculator works

This tool converts mass (grams) into volume (milliliters). Because different ingredients have different densities, there is no single universal grams-to-mL conversion. For example, 100 grams of water does not occupy the same volume as 100 grams of flour.

To get an accurate result, choose an ingredient preset or enter a custom density. The calculator then applies the standard conversion formula and gives an instant result.

The formula used

mL = g ÷ density (g/mL)

• g = mass in grams
• density = grams per milliliter
• mL = volume in milliliters

Common ingredient densities

Typical values used in cooking

• Water: 1.00 g/mL
• Milk: 1.03 g/mL
• Granulated sugar: 0.85 g/mL
• All-purpose flour: 0.53 g/mL
• Honey: 1.42 g/mL
• Olive oil: 0.91 g/mL
• Melted butter: 0.96 g/mL

Note: Density can vary slightly with temperature, brand, packing, and measurement method.

Why grams and milliliters are not always equal

Grams measure mass, while milliliters measure volume. Equal mass does not always mean equal volume. Dense substances (like honey) have more mass in less space, while less dense ingredients (like flour) occupy more space for the same mass.

Tips for better kitchen accuracy

• Use a digital scale for grams whenever possible.
• Use ingredient-specific densities for conversion, not a generic one.
• Level dry ingredients when measuring by volume.
• Keep in mind that temperature changes can affect liquid density.

Frequently asked questions

Is 1 gram always 1 milliliter?

No. That is only true for water at standard conditions. Most ingredients differ.

Can I use this for baking?

Yes. This calculator is especially useful in baking where precision matters.

What if my ingredient is not listed?

Select Custom density and enter the value in g/mL from a trusted source.
