The meter per second is the SI unit of speed. It expresses the distance traveled in a given time. One meter per second is equal to the speed of light in a vacuum. How do you write meters per second? The SI unit for velocity is the meter per second (m/s). To write meters per second, use the symbol "m/s". Does m·s Mean meters per second? Yes, m·s does mean meters per second. The SI unit for speed is the meter per second, so m·s is just an alternative way of writing this unit. Is velocity m/s or m/s s? There is no definitive answer to this question as different standards organizations may have different conventions. In general, however, velocity is typically expressed in units of m/s (meters per second). What unit is meter per second? Meter per second is the SI unit of speed. How do you write meters per second squared? There is no standard way to write meters per second squared, so you can choose any notation that you feel is clear and concise. For example, you could use "m/s^2" or "mps^2".
