How do I add a text string after my contour labels?

I'm new to using MATLAB and trying to add units to my contour labels, I've tried searching and I'm just ending up more confused.

My current code looks like this:

figure(1)
[C,H] = contour(PP,HH,Mfr*1000,mfrplot);
clabel(C,H,'manual');
grid on
hold on
[C,H] = contour(PP,HH,Pwr/1000,pwrplot);
clabel(C,H,'manual');

There are two different contours on the one plot, and I have the labels manually placed at the moment, due to overlapping text. How would I go about adding 'kg/s' and 'kW' units to the first and second contour labels?

I think I need to use t = clabel or tl = clabel but I'm not sure how that would look.

Thanks!

If I understood your problem correctly... I think the answer in this question will help you

they annotate their graph with numbers but you can use 'kg/s' and 'kW' units as well.
