For questions for chem in general, do you give the answer in the units that the question uses? I've been converting everything to the standard units (meters, liters, Kelvin, kilograms, seconds) regardless of what the equation gives. Am I supposed to keep the answer in the units that the question has? I really need to know before the midterm tomorrow so I don't get everything wrong!!!
Often time when you are done with a problem, the end result you get should be in standard units. But honestly I think any unit should be fine since they are refer back to the same amount (assuming you have the correct results).
Make sure when completing calculations you are using base SI units. These are units such as meters, seconds, and kilograms. This will ensure you are using the correct values in order to successfully cancel out other units. If you do calculations with centimeters, for example, you could end up with a completely different and incorrect result than if you first converted to meters. Prefixes like centi- and milli- are often used for convenience in answers and conversation but should not be used in calculation unless specifically noted in the problem.
