Temperature Calculator

The Temperature Calculator is a quick and accurate tool to convert temperatures between Celsius (°C), Fahrenheit (°F), and Kelvin (K). Whether you’re doing a science experiment, checking the weather, or following a cooking recipe — this tool makes conversion effortless.

How to Use the Temperature Calculator

Just enter a value in Celsius, Fahrenheit, or Kelvin, and the calculator will show equivalent temperatures in all three units instantly.

Temperature Conversion Formulas

• Celsius to Fahrenheit: (°C × 9/5) + 32
• Fahrenheit to Celsius: (°F − 32) × 5/9
• Celsius to Kelvin: °C + 273.15
• Kelvin to Celsius: K − 273.15
• Fahrenheit to Kelvin: (°F − 32) × 5/9 + 273.15
• Kelvin to Fahrenheit: (K − 273.15) × 9/5 + 32

Example

Temperature: 25°C
→ Fahrenheit = (25 × 9/5) + 32 = 77°F
→ Kelvin = 25 + 273.15 = 298.15 K

Common Use Cases

• Weather forecasting and checking climate data
• Cooking and baking recipes with unit conversions
• Scientific experiments and lab reports
• Engineering and HVAC calculations
• Educational reference for students and teachers

Why Use a Temperature Calculator?

Manually converting temperatures can lead to errors. This calculator saves time, ensures accuracy, and helps you switch between units effortlessly for any purpose.

Frequently Asked Questions (FAQs)

How do I convert Fahrenheit to Celsius?

Subtract 32, multiply by 5, then divide by 9.

What is Kelvin used for?

Kelvin is used in scientific calculations, especially in physics and thermodynamics.

What is absolute zero?

Absolute zero is 0 K, the lowest possible temperature where molecular motion stops.

Is there a quick Celsius to Fahrenheit trick?

Roughly: double the °C and add 30 for an estimate.

What’s room temperature in Kelvin?

Room temperature is about 20–25°C, which is 293–298 K.
