What does 1 ml weigh on grams?

Answer 1

Short answer: No. Since the first is a measure of volume and the second is weight, they are not equivalent.

Long answer: It depends on the substance being measured. With water, 1ml actually weighs about 1g. Other substance, no matter if they are solid or liquid, will weigh less or more.

Answer 2

1 g does not equal 1 ml.

A millilitre is a measure of volume, with dimensions [L3]. A gram is a measure of mass, with dimensions [M]. Basic dimensional analysis teaches that you cannot convert between measures with different dimensions such as these without additional information.

A ml of air has a mass substantially less than 1 gram while a ml of lead has a mass substantially greater.

Since the two are not equal, the rest of the question is irrelevant.

>> this is the most pedantic unhelpful answer to a question i have ever seen. clearly laid out to make the questioner look like a fool.

the answer is that 1gm of water DOES equate to 1ml of water (at 4c). this is partly what the metric system is based on.

the answer is right however, in that it depends on the density of what's being measured as to how many gm's equal a ml. 1ml of denser fluids will weigh more than a gram, and 1ml of less dense fluids or gases will weigh less than a gram.

Do you want a correct answer or one that keeps flatters your ego? I have no wish to make the questioner look like a fool. I simply wish to explain the thinking behind by answer.

In 1964 the definition of a litre was changed. As a result, 1 gram of water does not, repeat, does not, equal 1 ml at 4C and at a pressure of 1 atmosphere - despite what my critic, above, would have you believe. The density of water, at 4C and 1 bar is 0.999 972 grams per ml. Water has its maximum density at that temperature so at other temps the density is less than 1. The numbers are close to 1 but that is not the same as being equal to 1.

That is one of the problems with mathematics: the line between "the same" and "nearly the same". Would you say 1/3 = 0.3? 0.33? 0.33333? When do you stop? The two are never the same even though they may be approximately equal.

Answer 3

No, cm is a unit of length, ml a unit of volume and g a unit of weight.

Answer 4

This cannot be answered without knowing the density

Answer 5

It depends on the density of the substance.

13.1. Mmm. What would my sugar be

Answer 7

Yes
