Meet 21-year-old Mat George. He's a senior at Arizona State University.
George told BuzzFeed News that last Tuesday he posted this advertisement on Facebook.
His younger sister, proper owner of the appliance, responded to the listing.
And when a friend asked about the microwave's dimensions, George innovated.
Another ASU student, Rachel Sakelaris, 21, shared the vodka bottle measurement on Twitter. "I decided to tweet it because as funny as it was, it honestly didn't even surprise me," she said, "because that's a classic ASU move."
I love ASU
People really loved the new metric system.
@TMundlien @rachelsakk ASU #1 for innovation
"V accurate measuring technique," this person said.
