Powershell convert plain text to html

Question

I have some text in a text file like this:

Unit 1: abc

Unit 2: abc

And the list goes on an on to Unit 3,4,.. Is there any way to convert the content of this file to .html format? So that it would look like this (for example):

<p>Unit 1: abc</p>
<p></p>
<p>Unit 2: abc</p>

Googling hasn't really helped me on this one, thanks for your help!
