# Measurements

Commetior is a planet that relates to ancient Rome. Emile needs to help demolish buildings using a Roman onager and construct an aquaduct, use a time machine and collect the Gems that Scrambler has stolen. Knowledge of converting units including length, area, volume, masses, weights, time and dates are all required to stop Scrambler and his dastardly plans.
