Lengths beaten question

[Dices]

Does anyone knows how many feet does a length has ? (the way officials results calculate them). So if the second horse was 3 length behind the first how many feet is this? Is it calculated the same way regardless of race age ( lets say 3y only,4+,etc.),regardless of the race class etc?

Re: Lengths beaten question I don't think I've ever seen an 'official' length of a horse I reckon 9 feet would be approximately right........... :unsure
