Grouped by Topic
Good conversion tools do more than swap numbers. They make the unit system obvious, keep precision reasonable, and show when a conversion depends on context rather than math alone. For example, kilograms to liters and milligrams to milliliters can depend on the substance involved, not just the number entered. Data storage may differ depending on whether a context uses decimal or binary naming. Cooking and construction measurements can also require careful rounding so the answer stays useful in the real world. Use the unit labels as a second check before you trust the output.
