How to Convert Per Degree Fahrenheit to Per Degree Celsius

To convert per degree fahrenheit to per degree celsius, multiply the thermal expansion by the following conversion ratio: 1.8 per degree celsius/length/length per degree fahrenheit.

Since one length/length per degree fahrenheit is equal to 1.8 per degree celsius, you can use this simple formula to convert:

per degree celsius = per degree fahrenheit × 1.8

The thermal expansion in per degree celsius is equal to the thermal expansion in per degree fahrenheit multiplied by 1.8.

For example, here's how to convert 5 per degree fahrenheit to per degree celsius using the formula above.

per degree celsius = (5 1/°F × 1.8) = 9 1/°C

How Many Per Degree Celsius Are in a Length/Length per Degree Fahrenheit?

There are 1.8 per degree celsius in a length/length per degree fahrenheit, which is why we use this value in the formula above.

1 1/°F = 1.8 1/°C|1 1/°C = 0.5555556 1/°F

Our length/length per degree fahrenheit to length/length per degree celsius calculator automatically converts your thermal expansion measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.

Per Degree Fahrenheit and per degree celsius are both units used to measure thermal expansion. Keep reading to learn more about each unit.

What Is a Length/Length per Degree Fahrenheit?

A length/length per degree fahrenheit is a unit of thermal expansion equal to 1.8 per kelvin (1/K), the base unit for thermal expansion. Fractional expansion per °F (1/°F = 1.8 × 1/°C). [1]

The length/length per degree fahrenheit is classified as a US customary unit of thermal expansion. Per Degree Fahrenheit can be abbreviated as 1/°F; for example, 1 length/length per degree fahrenheit can be written as 1 1/°F.

When working with per degree fahrenheit (1/°F) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.

In practice, per degree fahrenheit (1/°F) are widely used across standard thermal expansion applications within US customary workflows, engineering documentation, and technical data sheets.

What Is a Length/Length per Degree Celsius?

A length/length per degree celsius is a unit of thermal expansion equal to 1 per kelvin (1/K), the base unit for thermal expansion. Fractional thermal expansion per degree Celsius. [2]

The length/length per degree celsius is classified as a metric and SI-compatible unit of thermal expansion. Per Degree Celsius can be abbreviated as 1/°C; for example, 1 length/length per degree celsius can be written as 1 1/°C.

When working with per degree celsius (1/°C) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.

In practice, per degree celsius (1/°C) are widely used across standard thermal expansion applications within SI metric workflows, engineering documentation, and technical data sheets.

When converting thermal expansion between per degree fahrenheit (1/°F) and per degree celsius (1/°C), keep full floating-point precision (1 1/°F = 1.8 1/°C; 1 1/°C = 0.5555556 1/°F) during intermediate calculations and round only the final length/length per degree celsius figure to match your instrument tolerance.
