Earth's Gravity as a Function of Latitude
The following table shows the relationship between latitude and the net acceleration due to Earth's gravity, local to each bicia·turn (b↓⊙) of latitude. Note that, except for the highest latitudes (above 28z b↓⊙ or 80°d), the deviation from 1 ⚀accelerel is always less than half a “pergross” or half a bicia (0.6%z), so local acceleration rounds to 1.00z ⚀accelerel (when rounded to the nearest bicia). Hence, assuming a local gravity of 1 ⚀accelerel is a fairly accurate approximation for most purposes.
