Use Golang to quickly implement unit conversion function

In today's society, unit conversion is an integral part of our lives. Whether in science, engineering or in daily life, we often encounter situations where we need to convert different units. In order to solve this problem, we can use the Golang programming language to quickly implement a unit conversion application. This article will introduce how to write a simple unit conversion application using Golang and provide specific code examples.

First, let’s determine which unit conversions need to be supported. In this example, we choose to implement conversions between length units, including meters, centimeters, inches, and feet. Next, we'll write a function to convert between these units.

package main

import "fmt"

func convertLength(value float64, fromUnit string, toUnit string) float64 {
    var result float64

    switch fromUnit {
    case "m":
        switch toUnit {
        case "cm":
            result = value * 100
        case "inch":
            result = value * 39.37
        case "ft":
            result = value * 3.281
        }
    case "cm":
        switch toUnit {
        case "m":
            result = value / 100
        case "inch":
            result = value / 2.54
        case "ft":
            result = value / 30.48
        }
    case "inch":
        switch toUnit {
        case "m":
            result = value / 39.37
        case "cm":
            result = value * 2.54
        case "ft":
            result = value / 12
        }
    case "ft":
        switch toUnit {
        case "m":
            result = value / 3.281
        case "cm":
            result = value * 30.48
        case "inch":
            result = value * 12
        }
    }

    return result
}

func main() {
    value := 1.0
    fromUnit := "m"
    toUnit := "cm"

    result := convertLength(value, fromUnit, toUnit)
    fmt.Printf("%.2f %s = %.2f %s
", value, fromUnit, result, toUnit)
}

In the above code example, we define a convertLength function, which accepts a floating point value, the original unit and the target unit as parameters, and then converts the relationship according to different units Calculate the converted result and return it. In the main function, we simply call the convertLength function to do the unit conversion and print the result.

In actual applications, this program can be extended as needed to add more unit conversion functions or implement other types of unit conversions. By using Golang, a fast and efficient programming language, we can easily implement various unit conversion functions, improve work efficiency, and make life more convenient.

We hope that the code examples provided in this article can help readers quickly implement the unit conversion function and find more interesting uses in practical applications.
