Interpretation of calculation methods for different spray bottle volumes

Then sometimes some friends use kilograms for calculation. What's going on? We must first know one condition. Our capacity is calculated based on water capacity, that is, it is calculated based on water density. Junior high school knowledge, mass = density x volume So usually it says: I want a bottle with a capacity of 1 kg, which is 1L, or a 1000ml bottle. Because the density of water is normally calculated as 1, we just need to keep this in mind. Let ’s summarize it below.
 
Many buyers sometimes mention the term capacity when purchasing spray bottles, but each one is called differently in each place. I will list them one by one in the future. Mixed up:
 
In spray bottle packaging, the most commonly used volume names are milliliters and liters. The unit symbol of milliliter is ml. The unit symbol of ml is L1L (liter) = 1000ml (ml). I really do n’t want to remember this friend. You can Baidu “capacity conversion” and it will be filled in for a form. Fill in what you want and it will automatically figure it out for you.
 
1 liter = 1000 milliliters = 1 kilogram = 1000 grams. That's it, don't learn too many others.
 
There are also some foreign trade companies. Many times they use OZ (ounces) to calculate. This is a little complicated. But this is also a formula ratio:
 
Liquid ounce: a unit of measurement of volume, the symbol is oz 1 imperial liquid ounce = 28.41 ml 1 US liquid ounce = 29.57 ml You can also Baidu click the word "ounce", then it will also come up with a calculator to let you fill in That's it, everyone can understand it. As for how to measure the water capacity, take the bottle and put it on the scale to see how many grams and then subtract the weight of the bottle. If it is cylindrical, but there is no scale, you can use the following formula to roughly Do the math, the volume is 3.14 x the square of the bottle radius x the height of the bottle.
