Yep but as American and British imperial measures often differ that wouldn't be very helpfull! Those cunning French grams are constant all over...
How true. My sailboat seems to be a hodgepodge of SAE, Metric, and British Imperial measurements. My water tank is in US gallons, however the fuel tank is in Imperial gallons. The exterior rigging and deck hardware is in SAE measurements, but the engine and transmission are in metric. Go figure!
