Sixteenths: Trade Calculator

Sixteenths is a construction calculator that works the way the trade works. You buy it one time. There is no subscription, no account, and no sign-in. It makes no network connections at all, so it works in a basement, a crawlspace, or anywhere else with no signal. EVERYTHING IN FRACTIONS Enter 6' 3 5/16" and get back 6' 3 5/16". The math underneath is exact fractions from end to end, not decimals rounded at the last second. When a result does not land cleanly on your chosen precision, the app tells you, instead of quietly handing you a number that is slightly wrong. Set your precision anywhere from 1/2 to 1/64. EVERY ANSWER SHOWS ITS WORK Tap any result to see the formula, your inputs, and each step. You should never have to take a calculator's word for it, and on a jobsite you should be able to check it in ten seconds. FOR ELECTRICIANS Offsets, 90 degree stub-ups, back-to-back bends, three-point and four-point saddles. Pick field multipliers, the rounded numbers you already use in your head, or exact trigonometry. The app always tells you which one it used. Bender tables for Klein, Ideal and Greenlee covering EMT, IMC and rigid from 1/2 inch to 4 inch. You can edit any of them or add your own bender, so your take-up is your take-up. FOR PIPEFITTERS Rolling offsets, travel, run and true offset at 11.25, 22.5, 30, 45 and 60 degrees, or any angle you like. FOR CARPENTERS AND GENERAL CONSTRUCTION Stairs solved in both directions: from your total rise, or from a total run you have to hit. Common, hip, valley and jack rafters, with the ridge thickness actually subtracted. Squaring and diagonals. On-center layout with every mark. Grade, fall and slope, including ADA ramp and drain-line checks. Sheet goods and roofing squares with a waste factor. Crown molding compound miter and bevel. Arcs and radius from chord and rise. MATERIALS Concrete in cubic yards, board feet, area and coverage. WHAT IT WILL NOT DO It does not size beams or headers. That is structural engineering, and a calculator should not pretend otherwise. Free: the full calculator and one solver pack, so you can judge it before you pay. One purchase unlocks everything, forever, on every device on your Apple ID.
