1. The conversion of 1 m/s to km/h is achieved by multiplying the speed in meters per second by a conversion factor of 3.6.2. This is because there are 1000 meters in a kilometer and 3600 seconds in an hour.3. Therefore, 1 m/s equals 1 * 3.6 km/h, which simplifies to 3.6 km/h.4. Alternatively, the conversion can be expressed as 1 m/s multiplied by (1 km/1000 m) multiplied by (3600 s/1 h), resulting in 3.6 km/h.
