To answer conversion questions like this go to Google.com and in the search window, type in your question like this..
24 cups in gallons
it will if you a direct answer.
It is great for this.
In your case type in
28 km in m
or
28 kilometers in meters
Note, you can also use the Google search window as a calculator. You might type in

If this is a homework question, the below is a very powerful and easy method to convert numbers from one unit to another.
Let us take an easy example.
Say you have 2.7 meters and you want to convert it to centimeters.
You know that 1m = 100 cm
Think about how we can take the equation 1m = 100 cm and divide both side by "1m" and get 1= 100 cm/m. (We have "re-arranged" the equation.)
Now think about how it is that if you multiply 2.7m by the number 1 you simply get 2.7m again.
Now think about how since "100 cm/m" equals 1 because 1= 100 cm/m you can multiply 2.7 m by "100 cm/m" and you will have the same distance. The only difference is that after you cancel out the meters the distance will be expressed in different units.
Here it is expresses mathematically...
2.7m = 2.7m X 1 = 2.7m X 100 cm/m = 270 cm. Notice how the meters cancel each other out and you are left with centimeters.
This always works
Here is a harder example.
Convert the speed 8,100 m/s to the units of km/hr
As discussed above since 1000m = 1 km, we will in this case divide both sides of the equation by "1000m" and get 1=(1/1000)km/m.
when we multiply by that and cancel out the meters, we get 8,100 m/s = 8.1 km/s.
(Note that we could have taken the equation 1000m = 1 km and divided both sides by "1km" to get 1 =1000m/km and then DIVIDED by 1000km/m and the meters would have still cancelled out. Here is the math 8,100m/s = 8,100m/s / 1 = 8,100m/s / 1000m/km = 8.1 km/s )
Now to convert the seconds to hours we first convert the seconds to minutes by taking the equation 1min = 60s and dividing both sides by "1min" to get the equation 1 = 60s/min
When we multiply 8.1 km/s by the above we get 480 km/min
We do the same thing with the equation 1hr = 60 min to get 1 = 60 min/hr and when we multiply, we get 28,800 km/hr which is in the correct units.
For some reason it is not the law for physic teachers to tell their students about this method.
Here is website that goes into it in more detail.

There are 28,000 meters in 28 kilometers. This is because there are 1,000 meters in a kilometer, so multiplying 28 by 1,000 gives you 28,000 meters.
1500 meters is 1.5 kilometers. To convert meters to kilometers, you need to divide the number of meters by 1000.
There are 166,000 meters in 166 kilometers.
There are 302,000 meters in 302 kilometers.
21 kilometers=21,000 meters21 kilometers = 21,000 meters
There are 28,000 meters in 28 kilometers. This is because there are 1,000 meters in a kilometer, so multiplying 28 by 1,000 gives you 28,000 meters.
there are 2,500 meters in 2.5 kilometers and 5,000 meters in 5 kilometers.
1500 meters is 1.5 kilometers. To convert meters to kilometers, you need to divide the number of meters by 1000.
4 kilometers are 4,000 meters.
6,378 kilometers=6,378,000 meters
There are 166,000 meters in 166 kilometers.
There are 302,000 meters in 302 kilometers.
21 kilometers=21,000 meters21 kilometers = 21,000 meters
100 cm in a meter 1000 meters in a km so 28 x 100 x 1000 = 2,800,000
670 meters=0.67 kilometers
49 kilometers = 49,000 meters
7 kilometers equal 7000 meters.
