I selected the correct answer in spite of my husband's lecturing me on why the metric system is more valuable since 1 milliliter equals 1 gram. I pointed out that was not the question I was asked to answer. (I may have also said something about do you want to cook your own dinner....) 🙂

Got it but only by guessing.

[Mike Nolan]

It is worth noting that 1 ml of water = 1 gram only under the specified conditions of temperature and atmospheric pressure, as well as the purity of the water, including dissolved gasses in it.

For years the definition of a meter was based on a master standard bar locked up in a Paris vault. However, that bar became distorted over time and as a result scientists recently adapted a new standard for length, one based on a reproducible physical property.

I got it wrong although I suspected there would be a twist to this. I have always operated under the assumption that 1 ounce of water by volume was also 1 ounce in weight.

[Mike Nolan]

It is pretty close to that, but there are times when the roughly 4% difference might be relevant.

I messed that one up.

[BakerAunt]

Those who missed it were probably mislead by the old adage: "A pint's a pound the world around." Clearly popular thought was wrong about that.

I even asked Alexa before I answered it and her answer was the same as mine.

[BakerAunt]

Alexa doesn't bake. 🙂
