Acerca de Convertidor de Temperatura

The Temperature Converter converts between all four common temperature scales: Celsius (°C), Fahrenheit (°F), Kelvin (K), and Rankine (°R). Enter a temperature in any scale and all other equivalents appear instantly without additional steps.

Celsius and Fahrenheit are the scales used in everyday weather and cooking. Kelvin is the SI unit used in physics and chemistry, with 0 K being absolute zero. Rankine is an absolute scale using Fahrenheit-degree intervals, used in some engineering contexts.

All conversions use exact formulas and run entirely in your browser with no server communication. Whether checking a cooking temperature, converting weather forecasts, or doing scientific work, results are accurate and instant.

Solución de problemas

Entering a Kelvin value below 0

Solución

Kelvin starts at absolute zero (0 K = -273.15°C). Values below 0 K are physically impossible. The calculator will not produce valid results for negative Kelvin inputs.

Forgetting that Fahrenheit and Celsius have different zero points

Solución

Celsius freezes water at 0° and Fahrenheit freezes water at 32°. This offset means you cannot simply multiply by a conversion factor — you must use the full formula: °F = (°C x 9/5) + 32.

Confusing °C and K for small differences

Solución

A temperature difference of 1°C is the same as a difference of 1 K. However, absolute values differ by 273.15. 0°C = 273.15 K, not 0 K.

Preguntas frecuentes

How do I convert Celsius to Fahrenheit?

Use the formula: °F = (°C x 9/5) + 32. For example, 100°C = (100 x 9/5) + 32 = 180 + 32 = 212°F.

What is absolute zero?

Absolute zero is the lowest theoretically possible temperature, at which all thermal motion stops. It equals 0 K, -273.15°C, or -459.67°F.

What is Kelvin and when is it used?

Kelvin is the SI base unit of temperature, starting at absolute zero. It is used in physics, chemistry, and engineering because its absolute scale simplifies thermodynamic equations.

What is the Rankine scale?

Rankine is an absolute temperature scale that uses Fahrenheit-degree intervals. 0°R = absolute zero = -459.67°F. It is primarily used in some US engineering and thermodynamics applications.

What is the freezing and boiling point of water in each scale?

Water freezes at 0°C / 32°F / 273.15 K / 491.67°R. Water boils at 100°C / 212°F / 373.15 K / 671.67°R at standard atmospheric pressure.

Can I convert negative temperatures?

Yes. The converter handles negative Celsius and Fahrenheit values correctly. Kelvin and Rankine, being absolute scales, cannot go below zero.

Is this useful for cooking conversions?

Yes. Many international recipes specify oven temperatures in Celsius, while US ovens often display Fahrenheit. Enter either value and get the other instantly.

Is my data private?

Yes. All conversions run entirely in your browser. No values are transmitted to any server.
