Cheat Sheet
- Abbe Gabriel Mouton's Decimal System - Ever wondered "what did Abbe Gabriel Mouton invent"? He introduced a decimal-based measurement system in 1670. By proposing to divide the Earth's meridian into ten million parts to define a unit of length, he laid the groundwork for the metre. 
- Defining the Metre and Metric Fundamentals - Building on Mouton's idea, the metre was later defined as one ten-millionth of the distance from the North Pole to the Equator. Grasping this Earth-meridian basis helps you understand why metric units scale so neatly by powers of ten. 
- Mastering Metric Prefixes with a Mnemonic - Metric prefixes (kilo-, hecto-, deca-, base, deci-, centi-, milli-) follow a strict tenfold pattern. A fun mnemonic - "King Henry Died By Drinking Chocolate Milk" - helps you recall kilo through milli; for example, 5 km×1000 m/km=5000 m. 
- Converting Angles: Decimal Minutes and Seconds - Abbe Gabriel Mouton's vision also included decimal minutes and seconds for angles, a concept still used when converting between degrees, minutes, seconds and decimal degrees. For instance, 30° 45′ becomes 30 + 45/60 = 30.75° in decimal form. 
- Applying Mechanics with Metric Units - Newton's second law, F = m·a, is simplest in metric units: mass in kilograms and acceleration in meters per second squared. If a 3 kg object accelerates at 4 m/s², you get F = 3×4 = 12 N - unit consistency guaranteed!
