Is 1 gram equal to 1 milliliter?

[candy terpenes]

I’m a bit confused about grams and milliliters. Does 1 gram of any substance equal 1 milliliter, or does it depend on the material? Can someone clarify this?

Not exactly — 1 gram is equal to 1 milliliter only for water at its maximum density (around 4°C). This is because grams measure mass, while milliliters measure volume.

For other substances, density differs, so 1 gram may occupy more or less than 1 milliliter depending on the material.

Example:

• Water: 1 g ≈ 1 mL
• Olive oil: 1 g ≈ 1.09 mL
• Mercury: 1 g ≈ 0.055 mL

It’s a special case for water, not a universal rule.
