Pretty much every other cream and soap uses grams for weight. The Proraso tubes are in ml, specifically 150. Anyone know about how many grams this would be? I'm assuming it's not 1:1 like water is.
Musgo Real uses ml (plus ounces) on their packages. I have a feeling it has to do with filling tubes versus bowls/tubs. As for the conversion, I have found it to be pretty much 1:1 in my 9 years of filling shaving cream samples.
Grams are for weight, milliliters are for liquid volume. The two aren't equal. For instance: 150 grams of gold will not fill a 150ml container. However, as we're not talking gold and we're talking liquid shave cream which is water based, they are very much rough equivalents.
true I agree, but measurement charts show 1ml of water weighs 1gr. it's confusing, but I guess that's the standard of measurement.
Charts show that because it is true for water, that's what the baseline is for both. So anything that's water based, like shave cream, is going to pretty much equal. It's just when you step away from water based things does it stop to make sense.
Part of the confusion is that gram is a measurement of mass and not weight. Oddly, in the US we use pounds/force for "weighing things". Weight and mass are not the same thing, exactly. Weight is the force of gravity acting upon a given mass. Mass is the amount of matter contained in an object. Water was used as the standard for mass of 1ml because water has a fairly stable density/noncompressibility profile as a liquid and is ubiquitous on earth.
Good description. 1 Liter of water weighs 1 Kilogram, etc. I personally find the pounds history more romantic, albeit more confusing, than the metric system.
The confusion arises in everyday speech. People say "weight" and "mass" imprecisely and interchangeably. Here's a link that explains it better. Mass never changes. Weight is dependent upon the force of gravity, which is variable, even on earth.
