I've seen some circuit diagrams on-line that appear to use the units prefix symbol as the decimal point. So a 6.8kΩ resistor is shown as 6k8 and a 1.2nF capacitor is shown as 1n2. Is this an accepted practice, and am I interpreting the values correctly?
This improves the readability of printed values on components. A decimal point may be overlooked or is just missing on bad printing quality. You can even find this practice on schematics, BOMS and components, that are 50+ years old. If you see 470 printed on a capacitor the value is not 470pF! You must read it in the code of the color rings on resistors: 4, 7 and no zero digits behind. It's 47pF then, 471 would be 470pF and 475 is 4.7uF. The same on inductors: 101 is 100uH, R27 is 270nH. Using R on an inductor is absurd but very common.
