About EngCalc Pro
Professional engineering tools built for engineers who need fast, reliable calculations in the field.
Built for the Field
EngCalc Pro was built out of frustration with existing engineering calculator websites — cluttered interfaces, poor mobile experience, and slow performance. Engineers working on site need tools that work fast, display clearly on a phone screen, and give reliable results.
Every tool in EngCalc Pro is designed with mobile-first principles. Large input fields, touch-friendly buttons, numeric keyboard triggers, and results that are easy to read and copy. Whether you're calculating pipe flow velocity on a construction site or converting pressure units in a control room, EngCalc Pro is built to help.
All formulas use industry-standard equations. Where assumptions are made (fluid density, gravity constant), they are clearly documented. The goal is transparency and reliability — tools you can trust for real engineering work.
Key Features
30+ Tools
Comprehensive engineering calculators and unit converters covering hydraulics, geometry, electrical, civil, and more.
Mobile-First
Designed for field engineers. Large touch targets, numeric keyboards, and one-hand-friendly navigation.
Instant Results
Real-time calculations as you type. No page reloads, no waiting. Results update instantly.
Works Anywhere
Responsive design that works on any device — phone, tablet, or desktop. No app install needed.
Reliable Formulas
Industry-standard formulas with clear documentation. Hazen-Williams, Darcy-Weisbach, Ohm's Law, and more.
Fast & Light
Optimized for speed. Works well even on low-end phones and slow mobile data connections.
Created by Ehab Basuoni
EngCalc Pro is created by Ehab Basuoni, an NRW Engineer with extensive field experience in hydraulic network design, DMA planning, smart metering, and NRW data analysis. Ehab built this tool to address the real needs of engineers working on site.
The tools and formulas are selected based on what field engineers actually use daily — from Hazen-Williams calculations to DN pipe references, pressure-head conversions, and pump power estimates.

EngCalc Pro is a client-side application. All calculations run in your browser — no data is sent to any server. Your favorites and recently used tools are stored locally on your device.
The application is built with React, TypeScript, and Tailwind CSS. It uses a responsive design system that adapts to any screen size, from small phones to large desktop monitors.
