How much is 3 grams in ml?

Answer 1

1 mL = 1 gram.

The above is only approximately true and only for pure water at a specific temperature. The reference given below shows that the value is always slightly less than 1. Originally the gram was defined so that it was exactly equal to water at 4 degrees Centigrade but this changed when the gram was redefined to be equal to a standard prototype mass.

Generally speaking, the question cannot be answered sensibly. A millilitre is a measure of volume, with dimensions [L3]. A gram is a measure of mass, with dimensions [M]. The two measure different things and basic dimensional analysis teaches that you cannot convert between measures with different dimensions such as these without additional information, such as the assumption that the mass in question is pure water at a specific temperature.

As a simple mental exercise consider a millilitre of air and a millilitre of water. They will have very different masses.

Answer 3

Grams are mass, millilitres are volume; they do not have a direct general relationship. If you know the density, you can work it out: mass divided by volume equals density.

Answer 4

This is not a valid conversion; milligrams (mg) and grams (g) are measures of weight or mass and mL (milliliters) is a measure of volume.

Answer 5

Depends what the 1.0 ml. substance is. If it's water it would weigh 1.0 grams. If it's Mercury it would weigh about 13.5 grams. The weight depends on the substance.

Answer 6

This cannot be sensibly answered. Milliliters (mL or ml) is a measure of volume, grams is a measure of weight or mass.

Answer 7

Grams can't be converted to milliliters. Grams measure mass, while milliliters measure volume.
