INTRODUCTION
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.
