Do crop/viewing percentages have a clear definition?

Sure, viewing pixels 1:1 or 100% crop makes a certain amount of sense, although those pixels could be displayed on a postage stamp or a billboard. I'm looking at a severe crop of a screech owl. Now the utilized pixels are 1370*1141. The camera's sensor is 4288*2848. How do you calculate the percentage crop?
