Standard form and SI prefixes

Physics regularly uses incredibly small or extremely large numbers. David Swinscoe looks at how we can simplify the mathematics involved using standard form, and how we can express these numbers quickly using prefixes

Physics is a science of measurements and precision, dealing with quantities that can be incredibly vast or minutely small. To handle these extremes scientists and engineers use standard form and SI prefixes, which simplify very large or very small numbers and enhance clarity. Mastering these concepts is crucial for both understanding and problem solving.

Standard form, also known as scientific notation, is a way of writing numbers that represents both very large and very small values in a concise and understandable manner. It expresses values as a number between 1 and 10 multiplied by a power of 10.
