History of changes, improvements and fixes to this calculator
2015.02.07 New implementation: This calculator has been rewritten. The previous implementation was server-side (made in PHP). Each time the new value was entered or any button clicked, the full website reload was triggered. Current implementation works fully client-side - it's written in JavaScipt. No more reloads !

"Calculla v1" version of this calculatorIn December 2016 the Calculla website has been republished using new technologies and all calculators have been rewritten.
