Cheat Sheet
- Inch to Centimeter Basics -
The inch-to-centimeter conversion is exact: 1 in = 2.54 cm, as defined by NIST standards. To convert inches to centimeters, simply multiply by 2.54 (e.g., 12 in × 2.54 = 30.48 cm). A handy mnemonic is "two and a half plus a smidge" to remember 2.54.
- Pounds and Kilograms Made Simple -
By international agreement (SI brochure), 1 lb = 0.45359237 kg. For quick estimates in your unit conversion quiz, round to 0.4536 and multiply (150 lb × 0.4536 ≈ 68.04 kg). Think "half a kilo minus fifty grams" to keep the factor in mind.
- Volume Swaps: Liters to Gallons -
The USGS defines 1 gal (US) = 3.78541 L, so 1 L ≈ 0.26417 gal. If you need to switch from liters to gallons in a metric to imperial conversion quiz, multiply liters by 0.264 (e.g., 3.8 L × 0.264 = 1.0 gal). Remember "three point eight five" to recall the gallon in liters.
- Mastering Temperature Formulas -
Converting Celsius to Fahrenheit uses F = (C × 9/5) + 32, and the inverse is C = (F − 32) × 5/9, a staple in NASA's engineering guides. For example, 25 °C × 9/5 + 32 = 77 °F. A quick tip: multiply by two, subtract a tenth, then add 32 for an approximate F value.
- Metric Prefix Power-Up -
Understanding SI prefixes - from kilo (10³) down to milli (10❻³) and beyond - is essential for unit conversion practice. Use the classic mnemonic "King Henry Died Monday Drinking Chocolate Milk" to recall kilo-, hecto-, deca-, deci-, centi-, milli-. This knowledge helps you tackle everything from nanometers to megawatts in your conversion of units quiz.
