¿Qué es Unit Converter?
A unit converter translates a numeric value from one unit of measurement to another using a fixed mathematical relationship between them. Length and mass conversions are purely multiplicative: every unit within a quantity is a scalar multiple of a shared reference, so one foot is defined as exactly 0.3048 meters and one kilogram is exactly 1000 grams. Temperature is the exception, because the Celsius, Fahrenheit, and Kelvin scales have different zero points, so a conversion requires both a scaling factor and an additive offset rather than a single ratio. This tool applies the correct formula per category, so 1 mile becomes exactly 1609.344 meters and 100°C becomes exactly 212°F, without rounding errors introduced by intermediate steps.
Cómo usar Unit Converter
- Pick a category: Length, Weight, or Temperature.
- Choose the unit to convert from and the unit to convert to using the two dropdowns.
- Enter the value you want to convert into the input field.
- Read the result in the output box and copy it with the Copy result button.

Errores comunes
- Confusing the metric ton (1000 kg) with the US short ton (about 907 kg) or the Imperial long ton (about 1016 kg) — the three differ by roughly 10%.
- Forgetting that temperature conversions need an offset as well as a scaling factor, which is the classic mistake of multiplying by 9/5 and omitting the +32.
- Treating the converter's last digit as physically meaningful when the underlying factor is non-terminating, such as meters to feet (1 / 0.3048).
- Expecting this tool to convert volumes such as gallons or pints — it covers only length, mass, and temperature.
Por qué usar esta herramienta
- All conversion factors use their defined exact values, so 1 mile is exactly 1609.344 meters rather than a rounded 1609.
- Temperature is handled with the correct offset formulas, so 0°C maps to exactly 32°F and to 273.15 K.
- Switching category instantly swaps the available units, so kilograms can never be compared against inches.
- Everything runs locally in the browser — no network round-trip and no value leaves the page.
