I am confused about the units used in Kepler's 3rd law. Is T supposed to be in years or days? Is R supposed to be in kilometers or meters? Is there ever an instance where one combination of units is preferable over another (for example, if you want to use the answers from Kepler's third law to find another variable in a different equation, such as mass). After searching online, it was suggested to use Astronomical Units, but I've never been taught with those.
I know it is a simple question, just can't find a clear and concise answer.
Thanks.
