Having a discussion with a colleague over sig figs and conversions. Original problem: find perimeter of 12.6 ft by 13.88 ft room and express answer in meters. 16.1 m or 16.2 m? Question is when to round? After finding perimeter in feet? 53.0 feet to meters = 16.2 meters or at the end? 52.96 feet = 16.1 meters?
