# Celsius()

### CELSIUS()

Temperature conversion Fahrenheit to Celsius

Syntax

`      CELSIUS( nDegreeFahrenheit ) --> nDegreeCelsius`

Arguments

<nDegreeFahrenheit> temperature in degree Fahrenheit

Returns

<nDegreeCelsius> temperate in degree Celsius

Description

CELSIUS() converts temperature values measured in the Fahrenheit scale to the Celsius scale.

Examples

```      // melting point of water in standard conditions
? celsius( 32.0 )      // --> 0.0
// boiling point of water in standard conditions
? celsius( 212.0 )     // --> 100.0```

Tests

```      celsius( 32.0 )  == 0.0
celsius( 212.0 ) == 100.0```

Compliance

CELSIUS() is compatible with CT3’s CELSIUS().

Converts a temperature value from Celsius into Fahrenheit
------------------------------------------------------------------------------
Syntax

FAHRENHEIT(<nCelsius>) --> nFahrenheit

Argument

<nCelsius> Designates a temperature in Celsius.

Returns

FAHRENHEIT() returns the converted temperature in degrees Fahrenheit.

Description

This function converts Celsius temperatures into Fahrenheit equivalents.

Example

Convert the following Celsius temperatures to Fahrenheit:

FAHRENHEIT(12.5)            // Result:  54.5
FAHRENHEIT(125.0)           // Result:  257
FAHRENHEIT(1250.0)          // Result:  2282
FAHRENHEIT(-155.0)          // Result:  -247```
