Percentage is one of many ways to express a dimensionless relation of two numbers (the other methods being ratios, described in our ratio calculator, and fractions). Percentages are very popular since they can describe situations that involve large numbers (e.g., estimating chances for winning the lottery), average (e.g., determining final grade of your course) as well as very small ones (like volumetric proportion of NOâ‚‚ in the air, also frequently expressed by PPM - parts per million).

Percentages are sometimes better at expressing various quantities than decimal fractions in chemistry or physics. For example, it is much convenient to say that percentage concentration of a specific substance is 15.7% than that there are 18.66 grams of substance in 118.66 grams of solution (like in an example in percentage concentration calculator). Another example is efficiency (or its special case - Carnot efficiency). Is it better to say that a car engine works with an efficiency of 20% or that it produces an energy output of 0.2 kWh from the input energy of 1 kWh? What do you think? We are sure that you're already well aware that knowing how to get a percentage of a number is a valuable ability.

). If our household's budget is \$2400 and we allocated 1 per mille of that to buying chewing gum, we would spend 2.4 dollars (2 dollars 40 cents) on annoying our teachers (well, 20 years ago it was not allowed in Polish schools. We do not know the rules nowadays ðŸ˜ƒ). It's pretty similar to how you find percentages. If you wanted to use percentage calculator to count per mille, simply use numbers 10x lower (0.2 instead of 2, 4 instead of 40). (Source: www.omnicalculator.com)
