Practice converting units

To start, I'll do one example on the board.

  1. Josh Beckett throws a fastball at 95 mph. What is this speed in meters per second?

Now it's your turn.

  1. What is the speed of light, expressed in furlongs per fortnight? (For those who aren't horse-racing fans, one furlong is one-eighth of a mile).

  2. You are in charge of designing a new warehouse for an electronics retailer. It's a big building: it covers one acre of land. The region occasionally suffers from heavy rainshowers, which can dump so much rain on the flat roof of the building that one full inch will accumulate. In other words, the roof will have to support 1.0 acre-inch of water.

    How much mass will that water have?
