Technically, it is possible to express speed in meters per minute (m/min) instead of meters per second (m/s). However, the choice of units for measuring speed is based on convenience and standardization, and using meters per second is the more widely accepted and practical choice for several reasons:
Consistency with the International System of Units (SI): The SI unit for speed is meters per second (m/s). The International System of Units is a globally recognized and standardized system used in scientific and everyday measurements. It promotes consistency and facilitates easy conversion between different units.
Commonly used units: Meters per second (m/s) is a commonly used unit of speed in scientific and engineering contexts. It is familiar to professionals working in these fields and allows for consistent communication of measurements and calculations.
Relationship with other quantities: Speed is often related to other physical quantities such as acceleration and force, which are also expressed in SI units. By using meters per second (m/s), the relationships and calculations involving these quantities become more straightforward and coherent.
Practicality and ease of use: Meters per second (m/s) is a convenient unit for everyday calculations and measurements involving speed. It provides a clear understanding of how far an object travels in a specific amount of time, and it aligns with common experiences and perceptions of speed.
While meters per minute (m/min) can be used to express speed, it is less commonly employed in scientific and technical contexts. It may find more utility in specific applications where minute-scale measurements are more relevant, such as certain industrial processes or specialized calculations. However, for general purposes and consistency with the SI system, meters per second (m/s) remains the preferred unit for speed.
