321.13 GBP/ 1.85 GBP = 174 keys (for astro)

$3164.46/$18.25= 173 keys (for me)

By scourge

541.54 CAD / 3.144 CAD = 172 keys

Due to conversions, we will make it 170

170 it is

Any errors in conversion, please do let me know.

Just realised I made a mistake on GBP to key ratio, it should be:

318.37/1.85 = 172.09 keys, round to 172 keys.
