Mathematical people - help needed! Old Mac boots

[MagicMelon]

Aghh driving me nuts trying to work out what size my pony takes in Old Mac G2's! I worked out he's a size 0 for his fronts and 1 for his hinds in Boa's. But the Old Mac sizing is totally different (why?!). So if anyone has 10 mins to spare, could you possibly work it out for me

Ive given up! Ive never been good at fractions!

Sizing chart is at http://www.boahorseboot.com. Click on "Old Mac G2" and then "Sizing" at the top. The tables there.

I measured my pony in inches, each hoof obviously differs but Ive given the max:

Fronts:
4.2" width
4.7" length
2.8" buttress (although dont think they need this?)

Hinds:
4.2" width
4.4" length
3.0" buttress

Try using metric measurements..... much easier! Have you read every word of the instructions? This is important as they will not exchange them if they dont fit unless they are spotless.
