Hi David,

We also teach you in Unit 3 the conversion between inches wc and psi:

1 psi = 27.7 inches wc

To figure out which choice is correct for Question 6, you have to do some converting of the answers to different units. It’s good practice for something you occasionally have to do in real life!
