Any disability income that is taxable will be taxed at your ordinary marginal rate (which, for most people, is between 10% and 28%).

About a dozen states do tax benefits, however, either the same way as the feds or only if you make over a certain amount of adjusted gross income.
1 Psi = 0.0689475729 Bar. Psi is defined as 1 pound of force per square inch. It is the primary pressure unit in united states and widely used in all kinds of applications. 1 pound per square inch (psi) equals to 6 894.75729 pascals.
A pressure that causes the Hg column to rise 1 millimeter is called a torr (you may still see the term 1 mm Hg used; this has been replaced by the torr). 1 atm = 760 torr = 14.7 psi. Bar (bar) The bar is nearly identical to the atmosphere unit. One bar = 750.062 torr = 0.9869 atm = 100,000 Pa. Millibar (mb or mbar) There are 1,000 millibar in one bar. This unit is used by meteorologists who find it easier to refer to atmospheric pressures without using decimals. One millibar = 0.001 bar = 0.750 torr = 100 Pa. Pascal (Pa)
