How do I convert one row of values using a unit conversion?

How do I convert one row of values using a unit conversion? For example, I have a row of data in a matrix that I want to convert from [km] to [m]...

PData = [2440 , 6051, 1737, 3390, 11.3, 2576;

330, 4870, 73.4, 624, 1.07E-5, 135;

3.7 8.87, 1.62, 3.71, 0.0057, 1.35]

I want this to be:

PData = [2.440 , 6.051, 1.737, 3.390, 0.0113, 2.576;

330, 4870, 73.4, 624, 1.07E-5, 135;

3.7 8.87, 1.62, 3.71, 0.0057, 1.35]
