I found a way. Not sure if it's the best:

time = "2:3"
factor = 100.0/60.0

time_parts = time.split(":")
minutes = int(float(time_parts[1]) * factor)
if ( len(str(minutes)) == 1 ): minutes *= 10 # to get 50 instead of 5
     time_new = "%s,%.02s" % (time_parts[0],minutes)
     print "%s -> %s " % (time,time_new)
