Is 100ml of Water Equal to 100g of Water? Understanding Volume and Weight
Learn why 100ml of water is nearly equal to 100g of water at room temperature and how temperature affects water's density.

Yes, 100ml of water at room temperature (approximately 20 degrees Celsius or 68 degrees Fahrenheit) is nearly the same as 100g of water. This is because water has a density of 1 gram per milliliter (1 g/ml), making the weight and volume of water interchangeable in these units. However, this equivalence changes with temperature fluctuation due to the expansion or contraction of water molecules, so it's most accurate at room temperature.
FAQs & Answers
- Why is 100ml of water approximately equal to 100g? Because water has a density of approximately 1 gram per milliliter at room temperature, meaning 100ml of water weighs about 100 grams.
- Does water always weigh the same for 100ml at any temperature? No, water's weight for 100ml varies slightly with temperature changes due to expansion or contraction affecting its density.
- How does temperature affect water density? As temperature increases, water molecules move apart causing the density to decrease; when temperature decreases, density increases as molecules contract.
