Mach to TAS
Queries like mach 0.82 to tas need OAT because TAS = Mach × a(T). Use ISA altitude to estimate temperature when OAT is unknown.
Mach ↔ TAS FAQs
Common questions about mach to tas.
Why does Mach to TAS need temperature?
TAS = Mach × local speed of sound, and speed of sound depends on outside air temperature.
What is TAS at Mach 0.82 and 15°C?
At ISA sea-level temperature (15°C), speed of sound is about 661.5 kt, so Mach 0.82 ≈ 542 kt TAS.
Is this CAS or IAS?
This tool converts Mach ↔ true airspeed. For CAS/IAS ↔ TAS, use the dedicated CAS/TAS calculator.
