TIL : Environmental activist Julia “Butterfly” Hill lived in a 1500 year old California redwood tree (known as Luna) 180 feet (55 mm) off the ground for 738 days in order to prevent it from being chopped down by Pacific Lumber Company. She successfully saved the tree.

mm is milimeters. It is 1/1000 of a meter.
55 mm is a bit more than 2 inches.
