TTYL I couldn't disagree more. Writing kW when you are asked for, for instance, the amount of energy require to boil 1-L of water, DOES demonstrate that the person has no concept of what units are to be used. It's like saying "Why did I get this wrong? The answer was -1024 and I wrote 1024. Don't I deserve partial credit? It's only off by the negative sign." No, the answer is off by over 2000. If you wrote 12 and the answer was actually 2017, would you expect credit? Wrong is wrong. The ONLY exception I could see is if a transcription error occurs- on my worksheet, the final answer is clearly written with kWh as the units, but I copied it over wrong. That's worth something, maybe. This attitude of "just one letter" or "just the negative sign" leads to sloppy workmanship which will ultimately get one into trouble.
