how to convert uint16 to string in golang?

Hi Friends 👋,

Welcome To aGuideHub! ❤️

To convert uint16 to string in golang, just use the strconv.FormatUint() method and pass your integer, it will convert uint16 to string.

As we know FormatUint() method accepts only uint64 show first we have to convert uint16 to uint64 using the uint64() method.

Important Points

Difference between int and uint

UInt does not allow for negative numbers.

uint’s and int’s max value

uint8  : 0 to 255 
uint16 : 0 to 65535 
uint32 : 0 to 4294967295 
uint64 : 0 to 18446744073709551615 
int8   : -128 to 127 
int16  : -32768 to 32767 
int32  : -2147483648 to 2147483647 
int64  : -9223372036854775808 to 9223372036854775807

Today, I will show you how do I convert uint16 to string in golang, as mentioned above I’m going to use the strconv.FormatUint() way.

The strconv package provide strconv.FormatUint() method.

Let’s start our Golang convert uint16 to string example

Convert uint16 to string example


package main

import (

func main() {
  var i uint16 = 180
  fmt.Println(i, reflect.TypeOf(i))

  s := strconv.FormatUint(uint64(i), 10)
  fmt.Println(s, reflect.TypeOf(s))

In the above example, we have converted uint16 to string and printed it in golang console. let’s check the output.


180 uint16
180 string
