ChemEnggCalc — The Complete Guide: Online Calculators for Chemical Engineering
ChemEnggCalc is a site that gathers online calculators for chemical engineering. Each calculator shows the formula it is based on, so you understand what is being computed rather than just getting a number. Use is free, with no registration, and the site is funded by advertising.

- Unit conversion — quick and convenient.
What to know
The site suits a quick check, practice and understanding a formula. It carries no accuracy guarantee, so any result that goes into a design must be checked against an authoritative source — a textbook, a standard or validated software. It is a helper, not a design tool.
