Answer 1

Make sure you have the:

CheckOnClick = true;

property set. You aren't showing the code on how you are toggling the check values, since it seems that if you select British Units, you presumable are unchecking SI Units.

Something like this, maybe:

private void unitToolStripMenuItem_CheckedChanged(object sender, EventArgs e)
{
    if (britishUnitToolStripMenuItem.Checked==true)
    {
        sIUnitToolStripMenuItem.Checked = false;
        label21.Text = "lb/hr";
        label22.Text = "lb/FT3";
    }
    else if (sIUnitToolStripMenuItem.Checked==true)
    {
        britishUnitToolStripMenuItem.Checked = false;
        label21.Text = "Kg/hr";
        label22.Text = "Kg/m3";
    }
}
