Gas Cubby automatically converts from one set of measurments to another so, if the units are ever changed, be sure to revert to the proper setting prior to entering any data.

Due to ever changing currency rates and the potential for conversion error, Gas Cubby does not convert from one currency to another. The currency symbol itself may be changed along with the region format, which is found in the Settings app under General > International > Region Format.

Odometer Decimal: Turn the decimal on or off in the odometer field.
