...we designed Calculla to do these things easily, quickly and free of charge.

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...)
  • we will also publish a variety of graphs and charts (coming soon)

How Calculla works ?

  • Top - 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
  • everything below "the top" - it's a main calculator part. The calculator or table or chart or anything else you've found on Calculla is displayed here. Most calculators are pretty straightforward to use. If something is advanced or just tricky - there is always a bit of good explanation in the text below calculator.
