Em values are relative values, meaning there has to be a base value. The default font size if no value is otherwise specified is 16px, so 1.75 em would be 16 * 1.75 or 28px. It's worth noting, however, that em values are proportionate to the context in which they are set, so if you have a div where you have set font-size: 30px;, 1.75em in that situation would be 52.5px.
