TBP yield to Simdis yield

  • Last UpdatedAug 14, 2026
  • 1 minute read

The 50% Simdis point and 50% TBP point can be converted:

Tt50 = Ts50

To determine the difference between adjacent point measurements use the following formula:

ΔTt = A*ΔTsB

where

  • ΔTt = Difference in TBP point in °F

  • ΔTs = Difference in D86 point in °F
