228 km/h to mph: Here's the Conversion Formula and Interesting Facts

**Conversion Formula

1 km/h = 0.621371 mph
228 km/h = 141.671 mph

**Interesting Facts

• The speed of sound at sea level is approximately 1,235 km/h (767 mph).
• The world record for the fastest car is held by the ThrustSSC, which reached a speed of 1,228 km/h (763 mph) in 1997.
• The average speed of a commercial airliner is around 800-900 km/h (500-560 mph).
• The Concorde supersonic jet could fly at speeds of up to 2,179 km/h (1,354 mph).

**Potential Applications

Transportation

• High-speed trains capable of traveling at hundreds of kilometers per hour
• Supersonic passenger aircraft that could significantly reduce travel times
• Urban air mobility (UAM) systems, such as electric vertical takeoff and landing (eVTOL) aircraft

Energy

• Wind turbines with larger blades that can capture more energy at higher wind speeds
• Hydroelectric dams that can generate more electricity from faster-flowing water
