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.
