  • Water freezes at 0°C (32°F, 273.15K) and boils at 100°C (212°F, 373.15K) at sea level.
  • For cooking, common oven temperatures are 180°C (350°F) for moderate and 200°C (400°F) for hot.
  • Room temperature is typically around 20-22°C (68-72°F) or about 293-295K.
  • Absolute zero (0K or -273.15°C) is the lowest possible temperature where all molecular motion stops.
  • A quick Fahrenheit to Celsius estimate: subtract 30, then divide by 2.

Frequently Asked Questions

Have questions? Here are the answers about Temperature Converter

What is a Temperature Converter?

A Temperature Converter is a free online tool that allows you to instantly convert temperature values between different scales including Celsius (°C), Fahrenheit (°F), and Kelvin (K). It's essential for cooking, weather forecasting, scientific research, international travel, and understanding temperature measurements.

What is Celsius (°C)?

Celsius (also called Centigrade) is a temperature scale where 0°C represents the freezing point of water and 100°C represents the boiling point of water at standard atmospheric pressure. It is the most widely used temperature scale globally and is the standard in most countries.

What is Fahrenheit (°F)?

Fahrenheit is a temperature scale where water freezes at 32°F and boils at 212°F under standard atmospheric conditions. It is primarily used in the United States, its territories, and a few Caribbean nations.

What is Kelvin (K)?

Kelvin is the base unit of temperature in the International System of Units (SI). It is an absolute temperature scale, meaning 0 K represents absolute zero, the theoretical temperature at which all molecular motion ceases. Kelvin is extensively used in scientific research.

How do I convert Celsius to Fahrenheit?

To convert Celsius to Fahrenheit manually, use the formula: °F = (°C × 9/5) + 32. For example, 20°C = (20 × 9/5) + 32 = 68°F. Our converter does this instantly, just type your Celsius value.

Is my data safe and private?

Absolutely! All temperature conversions happen entirely in your web browser using JavaScript. No data is ever sent to our servers, stored, or shared with third parties. This tool is 100% client-side, ensuring complete privacy.
