In honor of the individual I saw at the fair last summer wearing a sleeveless black t-shirt proudly depicting a bald eagle, a flag, and fancy text that said “wtf is a kilogram?” I will unapologetically use the metric system throughout this book.

Meters and liters and Celsius, oh my.

You will also see times in 24-hour format, because there are 24 hours in a day and each hour should have a distinct designation. If you see a time you don’t recognize, just subtract 12 and you’ll survive.

To my American audience, and hopefully one day my Liberian and Burmese readers, I’m sorry to say that we are skipping the arbitrary measurement system based on some dead dude’s foot.
