Metric System in Aviation: Importance and Usage Explained

Yes, aviation uses the metric system (also known as the International System of Units or SI) for many measurements. In fact, the International Civil Aviation Organization (ICAO) has mandated the use of metric units for certain aviation measurements since 1971.

For example, distances are measured in meters and kilometers, speed is measured in kilometers per hour (kph), and altitude is measured in meters or feet (depending on the region). The metric system is used for safety reasons, as it allows for more precise and accurate measurements and calculations.
