Square Millimeters to Square Centimeters Converter
A precision area converter for drafting, PCB design, and small-scale crafting. Features rounding controls and calculation history.
About
In detailed technical drafting and electronics design (PCB layout), measurements often toggle between millimeters and centimeters. While linear conversion is intuitive, area conversion requires a division by 100 ($10^2$). Misplacing the decimal point in these contexts can lead to component fitment issues or incorrect material yield calculations.
This utility is optimized for "micro-macro" transitions in crafting and design. Unlike generic converters, it offers a History Tape to track multiple calculations - useful when summing up areas of different components - and adjustable rounding precision to match manufacturing tolerances.
Formulas
The relationship derives from squaring the linear factor ($1 \text{ cm} = 10 \text{ mm}$).
