If you build or design things you know the
importance of working with accurate dimensions.
The most frustrating and costly construction
headaches can usually be traced to dimensional
errors.
INCHMATE+ is a calculator for people who work
with dimensions. The simple measurements 
Foot-Inch-Fraction (or fif)  you make with rulers
and tape measures become difficult and tedious
when you try to add and subtract them ... let alone
multiply and divide.
INCHMATE+ calculates these dimensions
automatically.
INCHMATE+ was designed to be incredibly easy
to use. It has a patented "self-prompting" system
leading you through the process of entering Foot-
inch-Fraction (or fif) dimensions.
INCHMATE+ accepts inputs to 1/16"... the practical
limit of accuracy for common building and design
projects.
