Temperature Converter
A temperature converter translates thermal readings between Fahrenheit (°F), Celsius (°C), and Kelvin (K) using exact thermodynamic conversion equations. By applying formulas like °C = (°F - 32) × 5/9, it confirms that water freezes at 32°F (0°C) and boils at 212°F (100°C) at standard atmospheric pressure.

How Do You Calculate Temperature Step by Step?
Convert 68°F to CelsiusTemperature: 68
Scale: Fahrenheit
Subtract 32: 68 - 32 = 36
Multiply by 5/9: 36 × (5 / 9) = 20°C
Final Solution:20°C (293.15 K)
