Have not got the tables with me, but you need to know:
The number of air-changes/hour recommended for that room.
The size of your room in m³.
From this, you can work out if your chosen fan will extract the correct quantity the above two figure of air. Multiply together the above 2 figures to get the extract rate.
Or for domestic bathrooms, is it 15 l/s?

There you are. 15 l/s is "unlikely to provide adequate ventilation
but may in some circumstance meet the customers requirement for building regulations."
But, by the air change method, you need 9" fans for both.
