Condbend: Bend Calculator

Condbend is a conduit bending and electrical calculator built for the people who actually bend pipe. FIELD NUMBERS, NOT CALCULATOR NUMBERS Ask an electrician for a 4" offset at 30 degrees and you get "marks 8 inches apart, shrink 1 inch." Most apps answer 8.000 and 0.268. Condbend shows the traditional field-table number first, with the exact trigonometric value next to it, so you can trust it without translating it. BENDING - Offset — marks, shrink, any angle - 3-point and 4-point saddle - Kick, and kick combined with a 90 - Rolling offset — rise plus roll to true offset - Segmented 90 — large radius in N shots - 90 stub-up — height minus take-up Every bend comes with a mark-the-pipe diagram drawn from the same geometry the math used, so what you see is what you measured. ELECTRICAL - Ohm's law - Voltage drop, single and three phase, copper and aluminium - Minimum wire size for a voltage-drop target FILL - Conduit fill - Box fill BUILT FOR A JOB SITE - Works fully offline. No signal required, and no account for the free tools. - Dark by default, high contrast, readable at arm's length. - Big targets you can hit with gloves on. - Fractions to 1/16", with a keypad that has fraction keys instead of a decimal point, because nobody measures in tenths of an inch. - Take-up is editable, because it belongs to your bender, not to us. ACCURACY IS THE POINT Every formula is unit-tested against published reference values. The test suite itself is verified: constants are deliberately broken to prove the tests catch them. Wire sizes come from the ASTM B258 formula and fill from published physical dimensions — never copied from a code table. FREE AND PRO Ohm's law, the 90 stub-up and voltage drop are free, forever, with no ads. Condbend Pro unlocks the rest: every bending calculator, every diagram, wire sizing, conduit fill and box fill. Yearly with a 7-day free trial, or a one-time lifetime purchase. Pro is tied to an account you create with Sign in with Apple or Google, so it moves with you to a new phone. IMPORTANT Condbend is a reference tool, not a substitute for the electrical code or professional judgment. Wire sizing, conduit fill and box fill results are estimates for planning only. Always verify against the current NEC / CEC / BS 7671 and your local amendments, and confirm take-up against your own bender before cutting or bending.
