I believe it stands for Horace Lawson Hunley, who was the developer of the submarine.
If you are asking about pencils, it represents a degree of hardness of the 'lead' as in H for hard, then 2H 3H 4H and up to 9H

It's the series letter. Unlike coins, bills dates are only changed under certain circumstances. Before the 1970s new dates were used only when the design changed. When a new Treasury Secretary or Treasurer was appointed, the Bureau of Engraving and Printing simply added a letter after the date. The relatively high letter H means that your bill was actually printed in the 1960s! Today, the date is usually changed when a new Treasury Secretary is appointed, in addition to design changes. A letter is added when a new Treasurer is appointed.

H. Krayenbu hl has written: 'Hernation of lumbar and intervertebral discs'
hypotenuse
NO!!! 'H' is Hydrogen There is no element with the symbol 'L'.
i would imagine it stands for high lob wedge since the degree is > 60 degrees.
The h stands for hecto- which means 100. So there are (4.5 x 100) or 450 liters in 4.5 hL.
It means hectoLiters. It has an exponential size of 10^2.
H-h h-l l-l
hl means hectoliter, which means one hundred liters
mov H , L mov is opcode H L are operands
Re-arrange this equation: L=length W=width H=height S=surface area S = 2(LW+HW+HL) S/2 = LW+HW+HL (S/2) - LW = HW+HL (S/2) - LW = H(W+L) ((S/2) - LW)/(W+l) = H
Hydrogen
Math is an abbreviation of mathematics: it is not an acronym. So the h does not stand for anything!
