Diophant Ancient Measures Converter has been developed and is distributed freely in memory of the ancient Greek mathematician Diophantos or Diophantus (was born between 200 and 214 CE and died between 284 and 298 CE)

Diophantos, the father of algebra, was a Greek mathematician from Alexandria. He is the author of Arithmetica in which he dealt with the solving of algebraic equations. His theorems led to tremendous advances in number theory. Diophantus was the first mathematician ever who recognized fractions as numbers. Diophantine equations are usually algebraic equations with integer coefficients, for which integer solutions are sought.

Diophantos's work can be read in classical Greek with Latin translation at:
Arithmetica, vol. I
Arithmetica, vol. II
