Units of Length Metric System. 7 g = __________ mg. 9 µl = __________ L 4. Lets try a quick conversion, we'll convert 0.0348 km into cm. For example, if you know that there are 2.54 centimeters in every inch (or 2.2 pounds in every kilogram or 101.3 kilopascals in every atmosphere), then converting between those units becomes simple algebra. Although this assumption seems logical at first glance, it leads to catastrophically wrong answers. How have plants developed so many strategies for reproductive success? The world's population will nearly double in your lifetime. The second way you can approach this problem is to treat the conversion from milli- to kilo- as one big step: Notice the answer doesn’t change; the only difference is the number of steps required to convert the units. Is there such a thing as The Scientific Method? When you’re working on a conversion that passes through a base unit, it may be helpful to treat the process as two steps, converting to and from the base unit. How will such changes affect life as we know it? Let’s try another example. What is the only usable form of energy for cells and how do we get it?
