Convert Fahrenheit to Centigrade Calculator

Temperature reading converter

Convert Fahrenheit and Celsius

Convert degrees Fahrenheit to degrees Celsius—historically called centigrade—or reverse the direction with the correct scale offset.

Result

32 °F = 0 °C

Freezing-point identity32 °F = 0 °C

Formula useddegrees Celsius = (degrees Fahrenheit − 32) × 5/9

Worked example

Convert 95 °F to degrees Celsius

1
Subtract the scale offset
95 − 32 = 63.
2
Apply the scale ratio
63 × 5/9 = 35.
3
Write the Celsius unit
95 °F = 35 °C.

Reading American temperature scales

Translate Fahrenheit readings into modern degrees Celsius

A Fahrenheit label on a thermostat, oven, weather report, or historical record is not converted by a simple ratio. First remove its 32-degree offset, then rescale the remaining interval.

Step-by-step guide · Reading American temperature scales

Subtract first: the offset belongs inside the parentheses

Reading formula: °C = (°F − 32) × 5/9
Freezing reference: 32 °F = 0 °C
Modern term: degree Celsius, not centigrade

Remove the Fahrenheit zero offset
Begin with the reading and subtract 32. For 95 °F, that leaves 63 Fahrenheit degrees above the Celsius zero reference.
Apply the interval ratio
Multiply 63 by 5/9 to obtain 35. The ratio changes the size of the degree interval after the scale origins have been aligned.
Attach the destination symbol
Write 95 °F = 35 °C. Parentheses prevent the common error of multiplying the original 95 by 5/9 and subtracting 32 afterward.

Translate Fahrenheit readings into modern degrees Celsius: The safest manual method mirrors the exact equation instead of trying to remember a one-step shortcut.

Centigrade survives as a search term, not the preferred unit name

Older documents and everyday speech may use centigrade for the hundred-step temperature scale. Modern SI writing uses degree Celsius and the symbol °C. The calculator recognises the historical wording in the page title because users still search for it, but the result and explanatory copy should use Celsius consistently.

This naming history is separate from the arithmetic. A document labelled centigrade usually intends a Celsius reading, yet an editor should preserve the document's context rather than silently rewriting an old calibration record. The tool performs the numerical conversion only.

Ovens and recipes

350 °F converts to about 176.67 °C, while a recipe commonly rounds the setting to 175 or 180 °C because appliance controls and cooking guidance use practical increments.

Weather and indoor settings

68 °F converts exactly to 20 °C, and 86 °F to 30 °C. These are convenient communication points, not guarantees about comfort or local conditions.

Temperature changes

A 9 °F change equals a 5 °C change and does not use the 32-degree offset. Readings and intervals must remain separate.

Follow the source scale into the right next calculation

When a forecast or metric recipe starts in Celsius, use the Celsius-to-Fahrenheit calculator rather than reversing the steps mentally. For scientific measurements expressed from absolute zero, the kelvin-to-Celsius calculator uses a different, offset-only equation.

Weather questions involving humidity need more than a scale change; the dew point calculator combines the relevant air measurements. The general converter also supports Rankine when that is the actual source. None of these pages calibrates an oven or sensor, and no valid Fahrenheit input may imply less than −459.67 °F, the Fahrenheit representation of 0 K.

Important limitations

This page converts absolute temperature readings, not temperature intervals. Values below 0 K are rejected, and water freezing or boiling references can vary with pressure, purity, and measurement conditions.

Review the stated scope, calculation method, assumptions, supported inputs, and effective dates, and obtain qualified advice before using a high-stakes result.
