Understanding Measurements: Grams vs Millilitres

When you see 100 millilitres (ml) of water, it typically weighs 100 grams (g). Simple, right? Well, only sometimes! The equivalence of weight (grams) and volume (millilitres) actually depends on the density of the substance being measured. Water is unique because it has a density of 1g/mL, meaning 100ml of water always weighs 100g. However, different liquids and solids vary in density, which can change things up.

For instance, cream is a bit thicker than water but is still surprisingly close to this 1:1 ratio, deviating by only 1-3% from water. This means that 100ml of cream roughly weighs 100g, making conversions simple. On the other hand, something like a sugary beverage has a slightly higher density. Regular Coke, for example, has a density of 1.042g/mL. So, a 330ml can would weigh about 343.86g—just a bit more than its volume suggests.

Why Does This Matter?

At Clubwell, we like to keep things straightforward, so we usually assume 1ml is about 1g, making it easier for you to understand nutritional labels and portion sizes...
