How to enter Fractions and Decimals
Length in
Centers in
Start At in

Enter measurements in inches. Enter fractions using a space between inch, fraction and fraction segments, eg: 23 3 4 = 23.75.
Enter Total Length, Centers and Start Point and tap Calculate to generate the list of running measurements. Tap 'Next' and 'Back' buttons to step through the list on you phone or tablet. Tap 'Lock' to lock the screen, so it will not scroll when you tap. The inputs are extra large for easy data entry, and the display is large so you can see it more easily in sunlight.
Tap any measurement in the displayed list to jump directly to that measurement in the large display.

Running Measurements On calculator pages that create running measurement lists (roof framing, stairs, baluster etc), click the 'Mark-out' links near each list to open a page similar to this to step through and mark out the running measurements. (Speech enabled on Phone or Tablet)

DON'T BREATH THE DUST If you're cutting blocks, concrete, stone or ANYTHING and there's DUST - DON'T TAKE THE RISK
Don't cut it, or cut it wet so there's NO DUST - Silicosis Sucks

How should we spell it?
