Here's why:

* SI standard: The meter per second is the standard unit of speed in the International System of Units (SI), which is the globally accepted system of measurement used in science and engineering.

* Consistency and simplicity: Using m/s across different fields ensures consistency and simplifies calculations and data analysis.

* Scientific accuracy: m/s provides a precise and accurate measurement of speed, allowing for more detailed and reliable scientific findings.

While other units like kilometers per hour (km/h) or miles per hour (mph) are used in everyday life, m/s is the preferred unit in scientific contexts.
