If a log's Dib is 8 inches, approximate DBH?

Explanation:
Diameters inside and outside the bark differ because bark adds thickness around the trunk. A handy rule of thumb is to convert DIB to DBH by multiplying by about 1.28. So with a DIB of 8 inches, DBH ≈ 8 × 1.28 ≈ 10.24 inches. The closest option is about 10.26 inches. Keep in mind bark thickness varies by species and individual trees, so this is a reliable estimate rather than an exact measurement.
