What potential issues can arise when converting font sizes from points to pixels in PHP for Google title lengths?

When converting font sizes from points to pixels in PHP for Google title lengths, a potential issue that can arise is the discrepancy in how different devices and browsers interpret pixel sizes. To solve this issue, it is recommended to use relative font sizes like em or rem, which are based on the font size of the parent element rather than an absolute pixel value. 

// Convert font size from points to em
function convertPointsToEm($points) {
  return $points * 0.75; // 1 point is approximately equal to 0.75 em
}

$fontSizeInPoints = 12;
$fontSizeInEm = convertPointsToEm($fontSizeInPoints);

echo "Font size in points: " . $fontSizeInPoints . "pt<br>";
echo "Font size in em: " . $fontSizeInEm . "em";
