🔍 Key Concepts

• SI (International System of Units) prefixes used in engineering and navigation electronics • The relationship between everyday terms like kilometer or kilogram and the base unit • How powers of ten (10^3, 10^6, 10^9, 10^12) scale numbers

💭 Think About

• Think about a kilometer compared to a meter: how many meters are in one kilometer? • Consider how many grams are in one kilogram; which power of ten does that represent? • Match that same factor you use for kilo in distance or weight to the choices given for voltage.

✅ Before You Answer

• Be sure you know that kilo is a standard SI prefix, just like mega and giga • Compare which prefix is normally used for a million (10^6) in electronics or data (e.g., megahertz, megabyte) • Confirm that the factor you associate with kilo in common words (kilometer, kilogram) matches the correct power of ten in the options
