7. The Difference Between Mass and Weight
Here’s an interesting point: did you know that mass and weight aren’t the same thing? Weight depends on gravity, while mass is the amount of matter in an object. This might not affect your day-to-day conversions, but it’s a cool fact to keep in mind if you’re dealing with scientific measurements.

For scientific purposes, though, you might need even more decimal places, but for most cases, two decimals do the trick.
9. Why Accuracy Matters in Scientific and Everyday Conversions
Why does accuracy matter? Imagine if you were working on a medical case where even small weight variations could affect dosages. Or, if you're shipping items internationally, minor errors in weight could lead to incorrect shipping fees.
