More data is needed. What is the material of the wire - copper -steel - etc. The physical units associated with the numbers are needed. Are they inches - ohms - etc. These units are needed. Please reformulate your query.
29.92 inches of mercury = ~406.78 inches of water.
The answer is 58.27 inches (approx.). Inches and centimeters are both units of linear measurement. Inches are used in the imperial system whereas centimeters are used in the metric system. To convert from cm to inches, multiply the cm unit by 0.393701.

A mechanical pencil is just about the same size as a normal pencil, about 6 inches long.
The mechanical advantage is the number by which the input force gets multiplied. Butsometimes you want to multiply the distance, and you don't care about the force.The first example that comes to mind is the car's windshield wiper. The motor at the bottomswings a little lever a few inches from side to side. The mechanical advantage of the wiper armis much less than '1', so the force at the end of the blade is much less than the force of the motor,but it sweeps all the way across the window.The distance is multiplied by the reciprocal of (1 divided by) the mechanical advantage, so if themechanical advantage is less than 1, the output distance is greater than the input distance.In some applications, that's exactly what you want.
72 inches by 42 inches. 72 inches by 48 inches. For outdoor use backboard surface area is reduced and the top and base is contoured to reduce wind resistance.
