While you’re walking down the street, walking slowly, you suddenly ask yourself, “Hey, how many moles are there in 35.6 grams of sulfuric acid?” Have you ever asked? Or worse, “How many cubic feet are in a 20 x 10 x 2 yard pool?” Questions, questions and more questions. Some may think, I wish there was a website with millions of calculators for everything that I could use completely free.

No, millions, but 3,634 calculators, yes.

Versatile Calculator. That’s the name of this amazing website with over 3,600 calculators for all kinds of things. It was developed by a Polish company of the same name and has been operating since 2014. According to the information provided by Omni Calculator, 20 million people turn to the calculator every month. There is also an adopted otter at the Warsaw Zoo, which is always a positive point.

14 episodes. All calculators are completely free and are divided into sections such as biology, chemistry, construction, ecology, finance, food, health. There are more collections within each section. For example, in the “Physics” section there are kinetics, energy and power, dynamics, statics, optics and light, astronomy calculators… Everything is very well organized. If we don’t know exactly which calculator we need, we can always use the search engine to have the platform suggest us a calculator.

The website is very intuitive. We just need to select the calculator, enter the relevant data and press enter. The website will do the rest. The good thing is that we can choose any unit, so if we talk about calculating volumes we can use liters, gallons, cups, ounces, cubic feet…

Descriptions. But beyond calculators, it is also interesting that each calculator has a corresponding description. For example, this calculator is used to know how many bricks we will need to build a wall. We can stay with the result, that’s all, but we can also read about how the calculation was done and the logic behind it. Or this calculator that even explains the formulas used for the speed of sound in solids.

Who made and studied it?. Another curious thing is that each calculator shows its author and reviewer. So we can see what kind of education the person who developed the calculator and reviewed it had. For example, this entropy calculator was developed by Julia, who has a bachelor’s degree in Biophysics and a master’s degree in Molecular Biotechnology, and was reviewed by someone with a master’s degree in Civil Engineering and another with a master’s degree in Pharmaceutical Sciences.
