Ruby Method Basics: Build a Miles-to-Kilometers Converter

Mastering methods is the foundation of writing clean, reusable code in Ruby. If you are new to programming, practicing with real-world calculations is the fastest way to build confidence. In this text-based course, you will learn how to design, write, and execute Ruby methods that perform unit conversions. By focusing on a practical miles-to-kilometers conversion exercise, you will understand how data flows into and out of your code. What you'll learn: - Understand core Ruby syntax for defining and calling methods - Accept inputs using standard parameters and modern keyword arguments - Perform arithmetic operations and handle float precision in Ruby - Return calculated values explicitly and implicitly from your functions - Write clean, readable code following modern Ruby style guidelines You will start with the fundamental terminology of Ruby programming, exploring variables and method definitions before moving on to practical coding exercises. Step-by-step written explanations will guide you through writing, testing, and refining your converter. This course is designed for absolute beginners who want a hands-on introduction to Ruby programming. No prior coding experience is required.
