Try entering various values into the different fields and see how quick and easy-to-use this handy tool is. Is only knowing how to get a percentage of a number is not enough for you? If you are looking for more extensive calculations, hit the advanced mode button under the calculator. Other than being helpful with learning percentages and fractions, this tool is useful in many different situations. You can find percentages in almost every aspect of your life! Anyone who has ever been to the shopping mall has surely seen dozens of signs with a large percentage symbol saying "discount!". And this is only one of many other examples of percentages. They frequently appear, e.g., in finance where we used them to find an amount of income tax or sales tax, or in health to express what is your body fat. Keep reading if you would like to see how to find a percentage of something, what the percentage formula is, and the applications of percentages in other areas of life, like statistics or physics.

So what is percentage good for? As we wrote earlier, a percentage is a way to express a ratio. Say you are taking a graded exam. If we told you that you got 123 points, it really would not tell you anything. 123 out of what? Now, if we told you that you got 82%, this figure is more understandable information. Even if we told you, you got 123 out of 150; it's harder to feel how well you did. A week earlier, there was another exam, and you scored 195 of 250, or 78%. While it's hard to compare 128 of 150 to 195 of 250, it's easy to tell that 82% score is better than 78%. Isn't the percent sign helpful? After all, it's the percentage that counts! 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. (Source: www.omnicalculator.com)

One percent is one hundredth. We use a % to indicate it. So 5 percent is the same as 5%, 0.05, 5/100 or five hundredths. It is that simple! That is nice, but we usually do not only use percentages. Sometimes we want to show the ratio between 2 numbers. For example: what is 40% of 20? That's 40 hundredths of 20, so if we share 20 cookies in 100 equal pieces (good luck with that!), 40 of those pieces are our 40% of 20 cookies. Let's count: 40/100 * 20 = 8. A little trick does apply here: if you want to divide by a hundred, just move the comma two places to the left. In our calculation, 40/100 * 20 we could also do so: (40 * 20) / 100 (it is the same). 40 * 20 is 800. Move the comma in 800 2 places to the left and you get 8.00. Enter these values at the top of the page, 40 and 20. Then you get "40% of 20 is 8". In another case you want to indicate, for example, how many percent a number has descended or increased. For example, if you have 10 apples and you eat 2 of them ... Then you have lost 20% apples. Why? Because 8 is 80% of 10. All apples were 100%, now we still have 80%, so the number of apples has descended by 20% (because 100 - 80 = 20). Use our percent increase tool for this.

We are sure that you're already well aware that knowing how to get a percentage of a number is a valuable ability. Although Ancient Romans used Roman numerals I, V, X, L, and so on, calculations were often performed in fractions that were divided by 100. It was equivalent to the computing of percentages that we know today. Computations with a denominator of 100 became more standard after the introduction of the decimal system. Many medieval arithmetic texts applied this method to describe finances, e.g., interest rates. However, the percent sign % we know today only became popular a little while ago, in the 20th century, after years of constant evolution.
