Key measurements are off

[ebolson1019]

The key measurements are all off, no key I know is .700in tall. Master is .281 not 700, all keys seem to have a similar problem and all associated measurements are off as if the whole drawing was improperly scaled.

It would definitely help if units were specified. Inches, centimetres, millimetres, ...?

This is indeed a units-conversion question. Master, like you said, @ebolson1019, is notated as 700, which refers to 0.700 cm. (This is indeed roughly 0.28 inches.)

The conversion factor for converting centimeters to inches is 0.3937.
This conversion comes from dividing 1 by 2.54, the conversion number for converting inches to centimeters.
There are 2.54 centimeters in 1 inch.

Using the conversion number of 0.3937, the conversion formula for converting x centimeters to inches is this:

x centimeters * 0.3937 = inches

All you have to do is to multiply your centimeters by 0.3937 and you will have your inches.
If you can remember the number 0.3937, then you will be able to convert your centimeters to inches that much quicker.
