How Many km/h is the Speed of Sound?
クイックアンサー
The speed of sound is approximately 1,235 km/h at sea level.
Speed of sound ≈ 1,235 km/h at 20°C
変換の理解
At 20°C and sea level, sound travels at 343 m/s = 1,235 km/h = 1 Mach. The speed of sound decreases with altitude as air gets colder; at 10,000 m (cruising altitude), it's about 1,062 km/h.
公式
Speed of sound ≈ 1,235 km/h at 20°C
一般的な例
| 説明 | 値 |
|---|---|
| Commercial jet (cruise at 900 km/h) | About Mach 0.73 |
| Concorde (Mach 2) | ≈2,470 km/h |
| Thunder distance calculation | Sound travels ≈343 m per second |
