Speed of sound converters translate between different units (m/s, km/h, mph, Mach) across temperature and medium conditions.
공식
Air (20°C): 343 m/s = 1235 km/h = 761 mph
- C
- 1235 km/h = 761 mph — 1235 km/h = 761 mph
- s
- 1235 km/h = 761 mph — 1235 km/h = 761 mph
- h
- 761 mph — 761 mph
단계별 가이드
- 1Air (20°C): 343 m/s = 1235 km/h = 761 mph
- 2Speed varies with temperature: adds 0.6 m/s per °C
- 3Mach number: speed / speed of sound in that medium
풀어진 예시
입력
1 Mach at sea level 15°C
결과
340 m/s, 1224 km/h, 761 mph
Breaking sound barrier
피해야 할 일반적인 실수
- ✕Using fixed Mach number without temperature/altitude correction
- ✕Assuming sound speed same in all media (water ~4.8×, solids even faster)
자주 묻는 질문
Why does sound speed vary with temperature?
Hotter air has faster molecular motion; molecules transmit sound faster.
Is Mach speed the same everywhere?
No, depends on temperature. Mach 1 at sea level ≠ Mach 1 at altitude (colder, lower speed).
