But now you can teach them how. And you can do it with any unit of measurement. 1ft 1meter. 1cm, 1kilometer. 1in. Your thumb.
And they will all be proportionately correct
I use mine craft... we can agree mine crafts square are the same size through out the world. And it hearts my head.. thinking about it.. because a 4ft square and an 8ft square are not what you imagine.
