Halloween High School Science Teachers Love Brains Apple Shirt
But the Halloween High School Science Teachers Love Brains Apple Shirt real fun comes in the conversion factor: one. The imperial ounce is one-thousandth of the weight of a cubic foot of water (on Earth), and the gram is (almost precisely) the mass of one cubic centimeter of water. For once everything cancels out and you don't need to convert the units. Like the sigh of relief when the temperature hits minus forty degrees. I used imperial units for a very short time for energy calculations. All the BTUs and Rankine temperatures were such a pain. Then I shifted to metric and life became so much simpler. Watts and Kelvin work so well together. The only time I use miles is either for distance or for speed and since 99% of my caring about speed is referencing a random number on my dashboard and making sure that it's close enough to a number on a sign, that wouldn't cause me any concern.
