How to choose the right converter
Start by identifying the measurement type you have now and the unit you want to end with. For example, choose a temperature converter for Celsius or Fahrenheit, a length converter for miles and kilometers, or a storage converter for MB and GB.
Some conversions use fixed ratios, while others use formulas. Distance, storage, and volume conversions usually use fixed unit relationships. Temperature conversions use formulas because the scales have different zero points.
When both a broad converter and a focused converter exist, use the broad converter for comparison and the focused converter for a faster one-direction result.
