CAIE IGCSE Biology EXTENDED 2.2.3 mm & micrometre conversions
Practise converting between millimetres and micrometres for cells, algae, pollen grains, beads and bacteria in paper calculations.
How this is tested
- convert actual cell or microorganism lengths from mm to μm and back again
- apply unit conversion before comparing specimen diameters or calculating size ratios
