ME255 March 27th

Today, during class time, professor gave back a homework that we handed in last week. He said he should put a unit convention in the homework but the unit that we need to use in that homework were just Minutes and $/Hours. When I was still wondering what unit convention he mean, he wrote 1 hour = 60 minutes on the board. He asked those people that convert 1 hour to 100 minutes don't be sad because they are not the first person that did that mistake.
