Very nicely done. If I were to tweak something....

Some have different names once you click on them.

- "Speed" is "Speed and Pace."

- "Data Size" is "Data Storage"

- "Fuel Economy" is "Fuel Consumption"

On the Data Size / Data Storage calculator, I would add kilobits, megabits, gigabits, and terabits. In addition to data storage, that might make it useful as a bandwidth calculator as well.
