Sexagesimal Conversions

The numerical system in Medieval Islamic mathematical and astronomical texts is mainly based on the sexagesimal system, which is based on 60 and not 10. Therefore, regularly the need arises to convert numbers between sexagesimal and decimal numbers.

There is no specialized software for this but several researcher have tackled this problem and tried to provide a solution:

  1. Seb Falck, from Cambridge University, has created an excel sheet which makes it possible to do numerical conversions between sexagesimal and decimal numbers and do computations with sexagesimal numbers.
  2. Victor Blasjo, from Utrecht University, has created a Mathematica notebook which makes it possible to convert sexagesimal numbers.
