KS2 Primary Maths Age 13-17 - Measure: Units and Conversions - Explained

The video tutorial explains how to convert 25 degrees Celsius to Fahrenheit using a thermometer that displays both scales. It demonstrates two methods to find the halfway point between two numbers: subtraction and addition. The first method involves calculating the difference between 86 and 68, then finding the midpoint. The second method adds the two numbers and divides by two. Both methods yield the same result of 77 degrees Fahrenheit. The tutorial emphasizes understanding and remembering these methods for finding midpoints.
