GCSE Biology - How to convert between nm, um, mm, m and km #4

The video tutorial explains the different units of length, such as nanometres, micrometres, millimetres, metres, and kilometres, and how to convert between them. It provides examples of converting units, like millimetres to metres and kilometres, and discusses the relative sizes of objects like atoms, molecules, and cells. The tutorial also covers the use of microscopes to view small objects and explains the position of centimetres in the scale of units, including conversion methods.
