title: Convert 'sp' font size to 'pt' font size
body: <p>I want to convert a font size 11sp to font size pt in xhdpi. The ratio for xhdpi should be 1:2.</p>
  
  <p>So, the calculation expected should be like:</p>
  
  <pre><code>11sp * 2 = 22pt (font)
  </code></pre>
  
  <p>But, it does not match actual font size in Zeplin UI. The font size should look like 14-16 pt. </p>
  
  <p>How to calculate the correct font size in pt from sp? </p>

  <p>I did search for this question and look though it before. It said the calculation should be 11 X 2. I understand and agree this calculation. But the UI do not agree this calculation. Can you let me know is there any wrong in my understanding?</p>
