I'm not sure if they will fit - these are the measurements I have for Scout: neck 35cm, chest 49cm, neck to chest 20cm, neck to tail 40cm
I'm fairly sure they're accurate, the sticking point being the 'join', the body belt bit. This is the part that's always too short in the harnesses we try on, and listed here as 5cm shorter than what I've measured! I'd love to try one on her, but can't afford to be stuck with a mistake :) I'll take a look at the suggested places and see if any will return ones that don't fit.
As for conversions, you can use google. Just type in "8 inches in cm" and it will return this. Handy!
