Relation Between Nanometres and Other Metric Units

Good question! To understand the relationship, let's look at the metric units:

• 1 nanometre (nm) = 10^-9 metres (m)
• 1 micrometre (µm) = 10^-6 metres (m)
• 1 millimetre (mm) = 10^-3 metres (m)

So, 1 nanometre is equal to 0.001 micrometres and 1 nanometre is equal to 0.000001 millimetres. This shows how small a nanometre is when compared to other metric units.
