Introducing the unit conversion function in the Golang programming language

Introduction to the unit conversion function in Golang programming language

In the Golang programming language, we often encounter situations where unit conversion is required, such as converting temperature from degrees Celsius to degrees Fahrenheit, convert length from meters to feet, etc. Golang provides a convenient and flexible way to perform unit conversion, making handling such needs simple and efficient.

1. Temperature unit conversion

package main

import (
    "fmt"
)

func celsiusToFahrenheit(celsius float64) float64 {
    return (celsius * 9 / 5) + 32
}

func fahrenheitToCelsius(fahrenheit float64) float64 {
    return (fahrenheit - 32) * 5 / 9
}

func main() {
    celsius := 25.0
    fahrenheit := celsiusToFahrenheit(celsius)
    fmt.Printf("%.2f摄氏度 = %.2f华氏度
", celsius, fahrenheit)

    fahrenheit = 77.0
    celsius = fahrenheitToCelsius(fahrenheit)
    fmt.Printf("%.2f华氏度 = %.2f摄氏度
", fahrenheit, celsius)
}

2. Length unit conversion

package main

import (
    "fmt"
)

func metersToFeet(meters float64) float64 {
    return meters * 3.28084
}

func feetToMeters(feet float64) float64 {
    return feet / 3.28084
}

func main() {
    meters := 10.0
    feet := metersToFeet(meters)
    fmt.Printf("%.2f米 = %.2f英尺
", meters, feet)

    feet = 32.81
    meters = feetToMeters(feet)
    fmt.Printf("%.2f英尺 = %.2f米
", feet, meters)
}

The above code example shows how to convert between Celsius and Fahrenheit and meters and feet in Golang unit conversion. By defining corresponding conversion functions, conversions between different units can be easily realized, and corresponding calculations can be completed by calling these functions in the program.

In short, in the Golang programming language, unit conversion is a common requirement. Through appropriate methods and function definitions, conversion between various units can be easily achieved. Mastering these conversion methods will help you write more flexible and practical programs.
