Excel: Converting Decimals to M:SS:000
<p>I'm looking to convert decimals into the format m:ss:000 or mm:ss:000. Either is fine. Here are a few examples of the input and the desired output:</p>

<ul>
<li>Input: 0.045173611 Output: 0:50.903</li>
<li>Input: 0.044722222 Output: 0:50.864</li>
<li>Input: 0.042256944 Output: 0:50.651</li>
</ul>

<p>I understand that the decimal input is a representation of how many days have gone by, but I just can't get the formula right. Thanks for any help you may have!</p>
