a few ways:
someone tells you who has measured the route (i.e. for events or well travelled routes);
you use an inclinometer which gives you the grade right at the spot you are standing;
you see a road sign that warns you of an impending 10% grade and you pee yourself cuz you're toting 100lbs of crap on a tour through italy . . .
