Which of the following speed conversions is correctly calculated?
1 m/s=3.6 km/h1 \text{ m/s} = 3.6 \text{ km/h}1 m/s=3.6 km/h
1 m/s=0.277 km/h1 \text{ m/s} = 0.277 \text{ km/h}1 m/s=0.277 km/h
1 km/h=1000 m/s1 \text{ km/h} = 1000 \text{ m/s}1 km/h=1000 m/s
1 km/h=3600 m/s1 \text{ km/h} = 3600 \text{ m/s}1 km/h=3600 m/s
