feet and inches are great if you're trying to make sure your couch fits in your living room, but if you're trying to design a vehicle that will fly you into space, you might want to go with metric, ya know?

Calories are definitely not imperial but they have been replaced in the ISU by joules.
The gram calorie approximates the energy needed to increase the temperature of 1 gram of water by 1 °C, as the passage indicates. This is equal to about 4.2 joules.
