Soil and Earthwork Calculator vs Elevator Calculator

Soil and Earthwork Calculator contains 60 Calculators for Soil Mechanics, Earthwork, Excavation, Compaction, Footing, Thrust from Soil, Explosion Calculations and Civil Engineering parameters. Available for iPad & iPhone Available in Imperial (USCS) and Metric Units (SI UNITS) Auto-fill Reference Values — select a Soil Type or Surface Material from the built-in picker and all input fields populate instantly with standard engineering reference values Built-in Reference Tables across 5 categories — Soil Properties (19 soil types), Atterberg Limits (15 classifications), Earthwork Materials (18 materials), Equipment Data (9 surface types + 5 scraper models), Water Conditions Smart Pass / Fail Banners — Relative Density, Percentage Compaction and California Bearing Ratio display instant colour-coded classification results (e.g. DENSE, PASS, GOOD / EXCELLENT) after calculation List of 60 Calculators : Water Content of a Soil Sample (Volumetric) Water Content of a Soil Sample (Gravimetric) Void Ratio Degree of Saturation Degree of Saturation (Based on Void Ratio) Porosity Dry Unit Weight of a Soil Specimen Relative Density of Cohesionless Soils (Based on Void Ratio) Relative Density of Cohesionless Soils (Based on Dry Unit Weight of Soil) Plasticity Index Liquidity Index Shrinkage Index Activity Saturated Unit Weight of Soil Dry Unit Weight of Soil Buoyant Unit Weight of Soil Coefficient of Internal Friction of Soil Vertical Stress in Soil (Boussinesq Equation) Vertical Stress in Soil (Westergaard Equation) Coefficient of Active Pressure Coefficient of Passive Pressure Total Thrust from the Soil (Walls retaining Cohesionless Soils) Total Thrust from the Soil (Walls retaining Cohesionless Soils & Surface behind the Wall is Level) Total Thrust from the Soil (Walls retaining Cohesionless Soils and are Completely Restrained) Total Thrust from the Soil (Walls retaining Cohesionless Soils and are Completely Restrained & Surface behind the Wall is Level) Total Thrust from the Soil (Walls retaining Cohesive Soils and are Free to Move a Considerable Amount) Total Thrust from the Soil (Walls retaining Cohesive Soils and are Free to Move a Small Amount) Total Thrust from the Soil (Highly Cohesive Soils) Total Thrust from Water retained behind a Wall Effect of Surcharge on a Wall retaining Cohesionless Soil / Unsaturated Cohesive Soil Stability Number (Slope - Without Seepage Water) Stability Number (Slope - Seepage of Water) Ultimate Bearing Capacity of Soil (Prandtl's Equation) Relationship between Loads on Foundations and Settlement Volume of Soil Percentage of Moisture Content in Soil Field Density of Soil Dry Density of Soil Percentage of Compaction of Soil Scaling Factor (Load-Bearing Test) California Bearing Ratio Flow Rate Compaction Production Rolling Resistance (Earth Moving) Grade Resistance (Earth Moving) Total Road Resistance / Total Pull (Earth Moving) Volume of Soil after Excavation Volume of Soil after Compaction Scraper Production Trips per Hour (Scraper) Amount of Material carried by a Machine Production Required Number of Scrapers needed on a Job Number of Scrapers a Pusher can Load Variable Time Wavelength of Vibration during Explosion Velocity of Particles distributed by Vibration during Explosion Acceleration of Particles distributed by Vibration during Explosion Overpressure due to Explosion Sound Pressure Level

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.
