How to Convert Grams to Milliliters
Converting grams to milliliters requires knowing the density of the material. Unlike simple unit conversions, this conversion depends on the substance because different materials have different densities.
Formula: Volume (mL) = Weight (g) ÷ Density (g/mL)
For example, water has a density of 1 g/mL, so:
• 1 gram of water = 1 mL
• 100 grams of water = 100 mL
Understanding Weight to Volume by Material Density
Why Water is 1 Gram to 1 Milliliter
Water has a unique density of exactly 1 gram per milliliter (1 g/mL) at room temperature. This is not a coincidence – the metric system was actually designed around water's properties. When the metric system was established, scientists defined 1 liter as the volume of 1 kilogram of pure water at 4°C (its maximum density), making 1 milliliter equal to 1 gram of water.
This special property makes water the perfect reference point for understanding density conversions. However, most other materials have different densities, which is why you need to know the specific density of each material to convert between grams and milliliters.
Real-World Examples
Cooking Examples
- • Granulated Sugar: 100g = 142mL (sugar is less dense than water)
- • Honey: 100g = 71mL (honey is denser than water)
- • All-Purpose Flour: 100g = 169mL (flour is much less dense)
- • Olive Oil: 100g = 109mL (oil is slightly less dense than water)
Scientific Examples
- • Table Salt: 100g = 82mL (salt is much denser than water)
- • Aluminum: 100g = 37mL (metals are very dense)
- • Cork: 100g = 417mL (cork is much less dense, floats on water)
- • Ice: 100g = 109mL (ice is less dense than water, which is why it floats)
Household Examples
- • Peanut Butter: 100g = 106mL (slightly less dense than water)
- • Coconut (shredded): 100g = 313mL (lots of air gaps make it less dense)
- • Brown Sugar (packed): 100g = 126mL (packing increases density)
- • Baking Powder: 100g = 110mL (chemical leavening agent)
Key Concepts to Remember
Dense Materials
Materials denser than water (>1 g/mL) will give you fewer milliliters than grams. Examples: honey, salt, metals.
Less Dense Materials
Materials less dense than water (<1 g/mL) will give you more milliliters than grams. Examples: flour, oil, sugar.
Pro Tip
When following recipes from different countries, always check if measurements are given by weight (grams) or volume (milliliters/cups). Converting between them requires knowing the specific ingredient's density, which is why professional bakers often prefer weight measurements for consistency!
