# Pressure units converter

This online conversion tool converts stress and pressure units from Metric to US to (UK) Imperial systems, and vise versa deals with all measurement values and conversions for any of the following **pressure or stress units**: atmosphere ( atm ), bar ( bar ), hectopascal ( hPa ), kilogram force per square cm ( kgf / cm^{2} – sq. cm ), kilogram force per sq. meter ( kgf / m^{2} – sq. m ), centimeters of mercury ( cmHg ), inches of mercury ( inHg ), dyne centimeter ( dyncm ), kilopascal ( kPa ), millibar ( mbar – mb ), millimeter of mercury ( mmHg ), pascal ( Pa ), microbar ( µbar – µb ), megapascal ( MPa ), kilo pound force per square inch ( ksi – kip ), pounds per square foot – feet ( psf , lb / ft^{2} – sq. ft ), foot poundal ( ft pdl ), pounds per square inch ( psi ), ton per square feet ( tsf ), ton per sq. inch ( tsi ), torr ( Torr ). Usefull e.g. for pumping air pressure into car tire – tyre.

Liked this conversion from atmospheres to Torr in the pressure converter. I deal with vacuum and partial pressures all the time so this is useful. Thank you.

Fast online converter kpa to hg inches of mercury in hg were my 2 pressure units for the exchange task. 1 kilopascal = 0.295333727 inches of mercury

The conversions I made were: 1 kilopascal ( kPa ) equals 0.30 inches of mercury ( inHg ). Fraction : 3/10 inches of mercury ( inHg ).

99 kilopascal ( kPa ) equals 29.234758060 inches of mercury ( inHg ). Fraction : 29 47/200 inches of mercury ( inHg )

100 kilo pascals ( k Pa ) equals 29.530058647 inches of mercury ( in Hg ). Fraction : 29 53/100 inches of mercury ( in Hg )

conversion kpa to in hg for pressure kilopascal=inch of mercury

Trading kilopascals into inch of mercury; 125kpa to inhg:

PRESSURE: 125 kilo pascal ( kPa ),

TRADES INTO: 36.91 inches of mercury ( inHg ),

AND FRACTION: 36 91/100 inch of mercury ( inHg ).

Where’s in the opposite- PRESSURE: 1 inch of mercury ( in-Hg ), TRADES INTO: 3.39 kilo-pascals ( 3.386 380 kPa ), & FRACTION: 3 39/100 kilo-pascal ( 3 193/500 kPa ) correct.

I want to know, an object weighing 67 tons exerts how many pounds per suare foot or per square inch?

Comment from/about : Carlos | Permalink

Well, what is Step 4 to get the converted number?

Comment from/about : Mimida | Permalink

I’d like to know how many mils ( milage ) are in a inch pressure in relation to air pressure in a car tyre and distance driven consequent.

A car tyre (average type) air pressure with the mileage closely relate, examples:

under-inflated tyre by ~10 % ( precent where the 24 PSI is the average usage and also norm ) gets the car a worst mileage by ~ 5 % loss

15 percent under-inflated car tires will result in ~ 10 percent milage loss

25 percent under inflated car tyre results in ~ 20 percent car performance loss.

The other way around; if a tire pressure is increased from those 24 to ~ 30 PSI during its life, the fuel mileage will also increase by 5%. As with tyre air pressure and mileage the same applies to the car tyres life span.
