nav menu spacing

I need to know the padding value that will put spaces in my ul li menu links.

You can see the clubmenu bar at

I would like more space between “Field” “Career Earnings” etc.

#clubmenu
{
position: relative;
text-align: center;
background-color: #fff;
height: 0.5em;
padding: 0.5em;
margin: 0 0 2px;
}

#clubmenu ul
{
padding:1em 0 0 0;
margin:0;
}

#clubmenu ul li
{
position: relative;
display: inline;
padding:0;
margin:0;
}

#clubmenu ul li a:link, #clubmenu ul li a:visited
{
        color: #fff;
	padding: 0.5em 1.0em 0.9em 1.0em;
	text-decoration: none;
	border:none;
}

#clubmenu ul li a:hover, #clubmenu ul li a:active, #clubmenu ul li.current_page_item a
{
        background-color: black;
	border: none;
}
