Convert the following to SI units:
a) 6.15 ms
b) 27.2 km
c) 112 km/h
d) 72 µm/ms

The uncertainty is computed as
Therefore, the uncertainty in the given mass is 1.95 kg.
We know that the formula for the distance traveled, d, if we are given rate, r, and time, t is given by
Therefore, the distance traveled is
Therefore, the distance traveled by the tectonic plate is about ☚
We need to convert 4.0 cm/year to km/My.
Therefore, the speed of the tectonic plates is 40 km/My. ☚
We know that 1 km=1000 m and 1 hr=3600 sec.
Convert 342 m/s.
Therefore, the speed of sound in km/hr is 1231.2 km/hr.
Convert 29028 ft to km
Therefore, the height of Mount Everest is 8.847 kilometers.
First, convert 6 ft to inches
Add the 1.0 inch
So, the total height of the person is 73 inches. We convert this to meters to come up with the desired unit.
So, the height of the person is 1.85 meters. ☚
