ErrorCalc-OUSL: Error Calculator for Physics & Chemistry Students
ErrorCalc-OUSL is an HTML-based error calculator for Level 3-5 Physics/Chemistry students at OUSL's Faculty of Natural Sciences. It computes absolute, relative, percentage errors, and propagation (add/subtract, multiply/divide) via a web interface. Install: git clone https://github.com/AbishekRKumar/errorcalc-ousl.git License: MIT 📖 Overview ErrorCalc-OUSL is a web-based tool designed to simplify error analysis for experimental sciences. Built with HTML, CSS, and JavaScript, it offers an intuitive interface for students to calculate errors directly in their browsers. Tailored for Level 3, 4, and 5 students at The Open University of Sri Lanka, it supports laboratory work by providing accurate calculations for absolute, relative, percentage errors, and error propagation. ✨ Features
Error Calculations: Computes absolute, relative, and percentage errors for measurements. Error Propagation: Handles addition/subtraction and multiplication/division error propagation. Interactive Web Interface: User-friendly form inputs with real-time results. Responsive Design: Accessible on desktops, tablets, and mobile devices. Educational Outputs: Displays results with explanations to enhance learning.
🚀 Getting Started Prerequisites
A modern web browser (e.g., Chrome, Firefox, Edge). No server setup required; runs locally as a static HTML file.
Installation
Clone the Repository:git clone https://github.com/AbishekRKumar/errorcalc-ousl.git
Navigate to the Directory:cd errorcalc-ousl
Open the Application:Open index.html in a web browser (e.g., double-click the file or drag it into your browser).
Dependencies
No external dependencies; uses vanilla HTML, CSS, and JavaScript. Optional: A local server (e.g., Live Server in VS Code) for development.
🛠️ Usage
Open index.html in a web browser. Select a calculation type from the dropdown: Absolute, Relative, and Percentage Errors Error Propagation (Addition/Subtraction) Error Propagation (Multiplication/Division)
Enter the required values (e.g., measured value, true value, uncertainties) in the form. Click "Calculate" to view results displayed below with clear explanations.
Example Output For Measured Value: 10.5, True Value: 10.0 Absolute Error: 0.5 Relative Error: 0.05 Percentage Error: 5%
