What do you not understand about it? The usual measurement in chemistry involve mass and volume. These are usually recorded in grams and liters. Other measurements such as mols, torr, atms, kelvins. The standard things you should know about measurements in chemistry is that
1. Converting mL to L by dividing by 1000
2. Converting Celsius to Kelvins by adding 273
3. Converting atm to torr by knowing that 1 atm is 760 torr.
4. Converting grams to mols by dividing the given number of grams and dividing by the molar mass of the compound.
