Conversion Calculators

307 calculators

We all use length, weight, temperature, time, speed, and various other quantities in everyday life. But they aren’t just plain numbers - they all have corresponding units. Moreover, the multitude of metric systems such as the International System of Units (SI) or the United States customary units (USC) complicates the situation even more. Is there a way to convert between units? How to memorize every unit in the world? Thankfully, you don’t need to do it! This pack of conversion calculators has been conscientiously prepared to serve you in almost every aspect of your life. They work both on the computer and on the smartphone so you can use them whenever and wherever you want. We also created many unusual calculators, such as the dog age calculator that finds the human age equivalent of your dog’s age, or the binary converter that lets you convert a number between binary and decimal systems. Check out Omni Calculators and make your life easier!
