Fahrenheit to Kelvin Conversion

Fahrenheit to Kelvin Converter

Convert Fahrenheit to Kelvin: This guide will explain how to convert Fahrenheit to Kelvin, show the relationship between these units, and provide examples for better understanding. By the end, you’ll be able to easily convert Fahrenheit to Kelvin.

Introduction to Fahrenheit

The Fahrenheit scale is a temperature measurement system commonly used in the United States. It is primarily used for everyday temperature measurements, such as weather forecasts and cooking. On the Fahrenheit scale, water freezes at 32°F and boils at 212°F under standard atmospheric pressure. This scale is different from the metric-based Celsius and Kelvin systems, which are used more widely around the world.

Some key facts about Fahrenheit:

• Water freezes at 32°F.
• Water boils at 212°F.
• Commonly used in the United States for weather and indoor temperature measurements.

Introduction to Kelvin

The Kelvin scale is an absolute temperature scale used in the scientific community. It starts at absolute zero, the theoretical point where all molecular motion ceases. Unlike Fahrenheit and Celsius, the Kelvin scale does not use the degree symbol (°). Instead, temperatures are simply expressed in kelvins (K). Water freezes at 273.15 K and boils at 373.15 K under standard atmospheric pressure.

Some key facts about Kelvin:

• 0 K is absolute zero, the lowest possible temperature.
• Water freezes at 273.15 K and boils at 373.15 K.
• Widely used in scientific calculations and research.

How to Convert Fahrenheit to Kelvin

To convert a temperature from Fahrenheit to Kelvin, you need to first convert it to Celsius and then to Kelvin. The conversion process involves two steps:

Step 1: Convert Fahrenheit to Celsius using the formula:

Celsius (°C) = (Fahrenheit (°F) - 32) × 5/9

Step 2: Convert Celsius to Kelvin using the formula:

Kelvin (K) = Celsius (°C) + 273.15

Combining these two steps, the formula to directly convert Fahrenheit to Kelvin is:

Kelvin (K) = (Fahrenheit (°F) - 32) × 5/9 + 273.15

This formula accounts for the differences in the freezing points and scale increments between the Fahrenheit and Kelvin temperature scales.

Celsius = (68 - 32) × 5/9 = 36 × 5/9 = 20°C

Kelvin = 20 + 273.15 = 293.15 K

Celsius = (-40 - 32) × 5/9 = -72 × 5/9 = -40°C

Kelvin = -40 + 273.15 = 233.15 K
