Kind of fun exercise (no good for British English).
def units(value, units='bytes'):
magnitude = abs(value)
if magnitude >= 1000:
for prefix in ['kilo mega giga tera peta '
'exa zetta yotta').split():
magnitude /= 1000.
if magnitude < 1000.:
break
elif magnitude < 1:
for prefix in ('milli micro nano pico femto '
'atto zepto yocto'.split():
magnitude *= 1000.
if magnitude >= 1.0:
break
if magnitude < .001:
return 'zero %s' % units
else:
prefix = ''
if value < 0:
return '-%.3f %s%s' % (magnitude, prefix, units)
return '%.3f %s%s' % (magnitude, prefix, units)
