Double-Check Numbers That Seem Wrong
If a conversion seems very big or very small, it might be wrong. A good trick is to do a rough check in your head. For example, you know that 1 kilometer is about 0.6 miles, so10 kilometers should be around 6 miles. If your converter says it’s 60 miles, something’s wrong!
Use the Right Category for Accurate Results
Make sure you pick the right type of conversion. For example, don’t use the volume converter when you need to convert weight, even though they might seem similar.
