convert bytes to mb using javascript code example

Example 1: javascrpt formatBytes

function niceBytes(x){
 const units = ['bytes', 'KB', 'MB', 'GB', 'TB', 'PB', 'EB', 'ZB', 'YB'];
  let l = 0, n = parseInt(x, 10) || 0;
  while(n >= 1024 && ++l){
      n = n/1024;
  }
  return(n.toFixed(n < 10 && l > 0 ? 1 : 0) + ' ' + units[l]);
}

Example 2: javascrpt formatBytes

function formatBytes(bytes, decimals = 2) {
    if (bytes === 0) return '0 Bytes';

    const k = 1024;
    const dm = decimals < 0 ? 0 : decimals;
    const sizes = ['Bytes', 'KB', 'MB', 'GB', 'TB', 'PB', 'EB', 'ZB', 'YB'];

    const i = Math.floor(Math.log(bytes) / Math.log(k));

    return parseFloat((bytes / Math.pow(k, i)).toFixed(dm)) + ' ' + sizes[i];
}

Example 3: javascript function convert bytes into mb

function bytesToSize(bytes) {
  const sizes = ['Bytes', 'KB', 'MB', 'GB', 'TB']
  if (bytes === 0) return 'n/a'
  const i = parseInt(Math.floor(Math.log(bytes) / Math.log(1024)), 10)
  if (i === 0) return `${bytes} ${sizes[i]})`
  return `${(bytes / (1024 ** i)).toFixed(1)} ${sizes[i]}`
}
