I don't believe it, but I've been reading my tape measure wrong all morning. My friend lost my Craftsman SAE tape measure last week and I'm still waiting on the replacement to come in.. found this metric one in the drawer and it's what I've been using since.:mad: I feel like a real idiot right now
Thank you so much guys!
