GCSE Maths - How to Use Conversion Graphs #80

The video tutorial explains how to use conversion graphs to convert between different units, such as miles and kilometres. It provides examples of converting 30 miles to kilometres and 75 kilometres to miles using a graph. Additionally, it discusses how to handle conversions for values not present on the graph by scaling known conversions.
