Let's talk about how to perform unit conversion in golang

Golang is an efficient programming language that has received widespread attention for its powerful features and high performance. In golang, sometimes you encounter some unit conversion problems, such as converting inches to centimeters, converting the speed of meters per second to the speed of kilometers per hour, etc. Therefore, this article will introduce how to perform unit conversion in golang.

1. Basic unit conversion

Golang provides a standard library-strconv, which provides many methods to complete basic conversions between numbers ( Such as string to number, number to string). The following are some basic unit conversion examples:

1. Length unit conversion

In golang, to convert inches to centimeters you can use the following code:

func InchToCm(inch float64) float64 {
    return inch * 2.54
}

2. Weight unit conversion

The method to convert pounds to kilograms is as follows:

func PoundToKg(pound float64) float64 {
    return pound / 2.2046
}

3. Temperature unit conversion

Convert Fahrenheit The method for converting degrees to degrees Celsius is as follows:

func FahrenheitToCelsius(f float64) float64 {
    return (f - 32) * 5 / 9
}

The above basic unit conversion methods can be widely used in actual development, and also provide us with some practical ideas.

2. Speed ​​conversion

In actual development, we also need to convert speed units. For example, convert the speed from meters per second to kilometers per hour.

1. Meters per second to kilometers per hour

func MpsToKmph(mps float64) float64 {
    return mps * 3.6
}

2. Kilometers per hour to meters per second

func KmphToMps(kmph float64) float64 {
    return kmph / 3.6
}

The above code It can well meet our needs in project development.

3. Area unit conversion

In actual development, we often encounter some area unit conversion problems, such as converting square feet into square meters.

1. square feet to square meters

func SqftToSqm(sqft float64) float64 {
    return sqft * 0.09290304
}

2. square meters to square feet

func SqmToSqft(sqm float64) float64 {
    return sqm / 0.09290304
}

where,sqft means square feet, sqm means square meters.

4. Summary

This article introduces the related methods of unit conversion in golang, including the conversion of basic units, the conversion of speed, and the conversion of area units. During the development process, we often encounter conversion problems with these units, so understanding these conversion methods can help improve development efficiency. At the same time, these methods can also provide us with some practical ideas so that we can better perform unit conversion in our daily lives.
