Solution: 54 km/hr. Need detail explanation? So Km/h is Kilometer per hour.Similarly, m/s means meter per second which is the unit of speed in SI. Average speed is distance traveled divided by time of travel. In this case, we want to convert miles to meters, so we need to know the fact that there are 1609 m in 1 mi. Add texts here. Now, the conversion of 80 m to kilometers is simply the use of a metric prefix, as we saw in the preceding section, so we can get the same answer just as easily by noting that, \[80\; m = 8.0 \times 10^{1}\;m = 8.0 \times 10^{−2}\; km = 0.080\; km,\]. Physics problems frequently ask you to convert between different units of measurement.

He loves to teach High School Physics and utilizes his knowledge to write informative blog posts on related topics. To convert km/hr value to m/s value just multiply the km/hr value with 5/18 and get the value in m/s. As example, 36 km/hr = 36 * (5/18) m/s = 10 m/s. Km/h to m/s or km/hr to m/s conversion: To convert km/hr value to m/s value just multiply the km/hr value with 5/18 and get the value in m/s. This failure to pay attention to unit conversions cost hundreds of millions of dollars, not to mention all the time invested by the scientists and engineers who worked on the project. So, for this unit conversion from kilometer/hour to meter/second, you need to remember the conversion …
You can use this method to convert between any type of unit. What is its speed in SI?eval(ez_write_tag([[300,250],'physicsteacher_in-box-4','ezslot_1',150,'0','0'])); Solution:Speed v = 90 km/hr = 90 * (5/18) m/s = 25 m/sSo the speed of the car in SI is 25 meter/secondeval(ez_write_tag([[336,280],'physicsteacher_in-banner-1','ezslot_4',151,'0','0'])); Anupam M is a Graduate Engineer (NIT Grad) who has 2 decades of hardcore experience in Information Technology and Engineering. The conversion factors we need are 1 kg = 103 g and 1 cm = 10−2m. In this case, you may need to convert units of feet or meters to miles. Anupam M is the founder and author of PhysicsTeacher.in Blog.
In this case, we know that there are 1000 m in 1 km.

Be sure the units in the unit conversion cancel correctly. We also want to convert minutes to seconds, so we use the conversion of 60 s in 1 min. (Note: Average speed is distance traveled divided by time of travel.). Here are some common conversions between units: The conversion between CGS and MKS almost always involves factors of 10 only, so converting between the two is simple. Let’s consider a simple example of how to convert units. Calculate average speed. This error caused the probe to follow a very different trajectory from what NASA thought it was following, which most likely caused the probe either to burn up in the Martian atmosphere or to shoot out into space. We see that the gram (“g”) in the numerator in 7.86 g/cm, Check that the units of the final answer are the desired units.

Often we find speed data or magnitude of velocity is given in Km/hr. So, for this unit conversion from kilometer/hour to meter/second, you need to remember the conversion factor as 5/18.Here Km means Kilometer and h or hr means Hour. However, other pieces of software that used these values for course corrections expected them to be recorded in the SI units of newton-seconds (N • s), as dictated in the software interface protocols.
