Calculators Online - smart, beautiful calculators, easy calculations

Welcome to Calculla

Calculla is just a collection of online calculators.
Some people say: "Calculla is like wikipedia with numbers instead of articles".

If you're looking to:
  • make a calculation (e.g. "how much interest will I pay on a mortgage ?" or "how much fuel my car will use over 200 km trip ?")
  • or convert (e.g. "10 Celsius degrees to Fahrenheit")
  • or just find some specific number in a table (e.g. "temperature of boiling water" or "size of the car tire")
  • or draw a nice looking pie chart
...Calculla is designed to do these things online.

On Calculla you'll find:
  • online web calculators - tools to calculate, convert, solve anything related to numbers
  • tables for various number collections (e.g how much dollars is for a Mexican peso or multiplication table or car tire size index or physical constants...)
  • soon we will also publish a lot of various graphs and charts

How it works ?

Your screen is divided into 2 sections:
  • Upper, yellow part - it's a search. Just type what you looking for in "search" input and Calculla will try to find the best calculators matching to it
  • Lower, black part - it's a main calculator part. Here is the calculator or table or chart or anything else you've found on Calculla. Most of the time it's pretty straightforward how to use given calculator, but if something is more advanced - there will be always good explanation of how it works on the same page

Have a nice Calcullations !
