UNIT SYSTEM
Presets
LENGTH
Bore, stroke, rod, manifold runners, valve dimensions
Example: 96 mm bore = 3.780 in
TEMPERATURE
IAT, autoignition temperature, charge cooling, knock zone
Example: 333 K = 59.9 °C = 139.7 °F = 599.4 °R
ΔT deltas (knock zone, charge cooling): 1 K = 1 °C = 1.8 °F = 1.8 °R
PRESSURE
MAP axis, atmospheric pressure, boost levels, EMAP
Example: 0 psig = 14.696 psia = 1.013 bar = 101.3 kPa = 29.92 inHg = 1.000 atm
SPEED
Laminar flame speed, turbulence intensity
Example: 0.42 m/s = 1.378 ft/s
CURRENT SELECTION
Length in
Temperature °F
Pressure psig

All values are stored internally in SI units (mm, K, psia, m/s). Changing units updates the display only — no data is lost or altered. Re-compute after changing units to refresh all tables.
