تحويل كيلومتر في الساعة إلى أقدام في الثانية: الطيران والنقل والهندسة

100 kilometers per hour equals 91.1344 feet per second. This conversion is commonly needed for vehicle performance specifications and aviation calculations. To convert, multiply km/h by 0.911344. For example, a car traveling at 100 km/h (typical highway speed in Europe) is moving at 91.13 ft/s, which helps engineers calculate stopping distances and aerodynamic drag forces using imperial-based formulas.

Aviation developed using feet per second because altitude and climb rates were naturally measured in feet, creating a consistent three-dimensional measurement system. Automotive industries adopted kilometers per hour following the metric system's global adoption for land transportation. International aviation standards (ICAO) mandate feet per second for safety-critical calculations, while ground transportation follows regional preferences. This historical divergence created the need for precise conversions between these systems in modern engineering.
