The calculator that speaks your language: feet, inches, and fractions. Elevator Calculator is a field calculator built specifically for elevator mechanics and constructors. No generic construction fluff - every tool maps to work you actually do in the hoistway. TAPE-MEASURE CALCULATOR - Add, subtract, multiply, and divide in feet-inches-fractions (down to 1/32") - Integer math under the hood - answers are exact, never 5.999999' - One-tap unit toggle: feet-inches, decimal feet, decimal inches, metric - Calculation tape and memory, just like the desk calculator you grew up on ELEVATOR TOOLS - Hoistway: total height, rail length, and bracket count from floor data - Rope/cable length with roping ratio, sheave wraps, and termination allowance - Clearance checker: pit depth and overhead PASS/FAIL by rated speed - Bracket spacing layout, standard or seismic ELECTRICAL TOOLS - Ohm's law solver - enter any 2 of V, I, R, P - NEC voltage drop calculator with 3%/5% pass/fail - Wire gauge reference: resistance and 60/75/90 degree C ampacity, 14 AWG to 500 MCM - NEC 240.4(D) small-conductor breaker limits noted right in the table BUILT FOR THE FIELD - Dark, high-contrast UI readable in a machine room - Works completely offline - no signal in the pit, no problem - No account, no ads, no subscription Reference values are typical industry minimums - always verify against ASME A17.1, the NEC, and your job specs. If you spend your day converting 7' 6-3/8" in your head, this one's for you. ## Key features - Feet-inches-fractions math - Hoistway dimension calculator - Rope/cable length calculation - Clearance checker - Ohm's law solver - NEC voltage drop calculator - Offline functionality ## Frequently asked questions about Elevator Calculator ### What units does Elevator Calculator support? Elevator Calculator supports calculations in feet-inches-fractions, decimal feet, decimal inches, and metric units. It allows for precise fractional calculations down to 1/32". ### Does Elevator Calculator work offline? Yes, Elevator Calculator is designed to work completely offline. This ensures functionality even when there is no signal available in areas like elevator pits. ### What specific elevator-related calculations can Elevator Calculator perform? It can calculate hoistway total height, rail length, and bracket count. It also computes rope/cable length with roping ratio and sheave wraps, and checks pit depth and overhead clearance against rated speed. ### Are there any ads in Elevator Calculator? No, Elevator Calculator is ad-free. The app explicitly states 'No account, no ads, no subscription'. ### What electrical calculations are included in Elevator Calculator? The app includes an Ohm's law solver for voltage, current, resistance, and power. It also features an NEC voltage drop calculator with 3%/5% pass/fail indicators and a wire gauge reference table. ### Is Elevator Calculator suitable for beginners? While built for professionals, the app's clear UI and specific tools cater to the direct needs of elevator mechanics. Its focus on exact calculations and industry-specific functions makes it a valuable tool for those in the trade. ### How accurate are the calculations in Elevator Calculator? Elevator Calculator performs integer math under the hood, ensuring exact answers without rounding errors. It provides precise results for all measurements, including fractions down to 1/32". ### What is the age rating for Elevator Calculator? Elevator Calculator has an age rating of 4+. This indicates it is suitable for users of all ages, with no content restrictions. ## Version history (last 3 releases) ### 1.1.1 — 2026-08-03 NEW: Pipe Bend calculator in the Electrical tab — offset bends (10°–60° with multipliers and shrink built in), 90° stub-ups with EMT take-up deducted automatically, and 3-point saddles.
