- To convert from a smaller unit to a larger unit, divide by 10 for each step up the metric scale (move the decimal point one place to the left per step).
- To convert from a larger unit to a smaller unit, multiply by 10 for each step down the metric scale (move the decimal point one place to the right per step).
- Use the mnemonic “King Henry Died Unusually Drinking Chocolate Milk” to remember the order of metric prefixes: Kilo, Hecto, Deca, Unit, Deci, Centi, Milli.
- Each prefix represents a power of 10 relative to the base unit (meter, liter, gram).
- For example, converting 5 kilometers to meters: since kilo is 3 steps larger than the unit, multiply 5 by 10 three times (5 × 1000 = 5000 meters).
Parent Tip: Review the logic above to help your child master the concept of metric to metric conversion.
