    Both my Labradors weigh more than 75 pounds! And they are not even overweight. Here’s where variation can get you. English or American Labs? Male or female? 🙂 Cultural differences can also get you when you least expect it: I once said an opening was the size of a “doggie-door” and the British publication’s copyeditors changed it to a “cat-flap” which I think of as being considerably smaller!

    I think is useful for checking sizes/amounts/volumes of things when I have it in one measurement and need it in another.

    Whoa that would be a tall bison! They can reach 11.5 feet in length, not in height.

    Some great tips/guidelines in here, thanks!
