Temperature Converter
Convert between Celsius, Fahrenheit, and Kelvin.
About the Temperature Converter
The temperature converter instantly converts between Celsius, Fahrenheit and Kelvin — the three scales you meet in cooking, weather forecasts, science and engineering. In Pakistan, daily life uses Celsius, but recipes, foreign weather apps and technical manuals often quote Fahrenheit or Kelvin, making a reliable converter essential.
The mathematics behind the scales is simple and exact: Celsius and Fahrenheit share a linear relationship where a 1°C change equals a 1.8°F change, and 0°C equals 32°F. Kelvin is Celsius shifted by 273.15, with 0 K — absolute zero — the physically lowest possible temperature. The converter applies these exact relationships, so results are precise to two decimal places.
Everyday uses abound: converting a recipe's 350°F oven to Celsius (about 177°C), checking whether a fever of 38°C matches the 100.4°F threshold used internationally, or understanding why a scientific paper's 300 K is roughly room temperature (about 27°C).
For weather, note that Pakistan's official forecasts and heatwave warnings are issued in Celsius — a summer day of 45°C is 113°F — and the converter makes those comparisons immediate when reading international coverage. For cooking, remember that Pakistani ovens are often marked in both scales; when a recipe says 200°C, that is approximately 392°F.
The converter supports all six direction combinations: C to F, F to C, C to K, K to C, F to K and K to F, each updating live as you type.

Frequently Asked Questions
How do I convert Celsius to Fahrenheit?
Multiply by 9, divide by 5, then add 32: (°C × 9/5) + 32 = °F. For example, 25°C equals 77°F.
How do I convert Celsius to Fahrenheit manually?
Multiply the Celsius value by 9, divide by 5, and add 32. For example, 25°C: (25 × 9 ÷ 5) + 32 = 77°F.
What is absolute zero?
Absolute zero is 0 K (−273.15°C or −459.67°F), the lowest possible temperature where molecular motion is at a minimum. It is a fundamental limit in physics.
Why does Pakistan use Celsius?
Pakistan, like most countries worldwide, uses the metric system and reports weather and body temperature in Celsius. Fahrenheit remains common in the United States and in older recipes and manuals.
