What is Mach 1 in meters per second (ISA sea level)?
Mach 1 is taken as 340.29 m/s here (ISA sea level reference used on this site).
Detailed answer
Mach number is speed relative to the local speed of sound, which varies with temperature. For a fixed calculator, this project uses a single ISA sea-level reference: Mach 1 = 340.29 m/s. Always treat Mach as approximate unless you use ambient conditions.
Relationship context
Aerospace reporting mixes Mach with m/s or knots; students often need a concrete m/s anchor for problems.
