The unit of hardness given by the test is known as the Vickers Pyramid Number (HV) or Diamond Pyramid Hardness (DPH). The hardness number can be converted into units of pascals, but should not be confused with pressure, which uses the same units. The hardness number is determined by the load over the surface area of the indentation and not the ...
6.894757 kPa. The pound per square inch (abbreviation: psi) or, more accurately, pound-force per square inch (symbol: lbf/in2), [1] is a unit of measurement of pressure or of stress based on avoirdupois units. It is the pressure resulting from a force with magnitude of one pound-force applied to an area of one square inch.
Ultimate tensile strength: typically 1.6–2.5 GPa (230–360 ksi). Grades exist up to 3.5 GPa (510 ksi) Elongation at break: up to 15%; K IC fracture toughness: up to 175 MPa·m 1 ⁄ 2; Young's modulus: 210 GPa (30 × 10 ^ 6 psi) [27] Shear modulus: 77 GPa (11.2 × 10 ^ 6 psi) Bulk modulus: 140 GPa (20 × 10 ^ 6 psi)

1.6 HBS 10/100 Hardwood: 2.6–7.0 HBS 10/100 Lead: 5.0 HB (pure lead; alloyed lead typically can range from 5.0 HB to values in excess of 22.0 HB) Pure Aluminium: 15 HB Copper: 35 HB Hardened AW-6060 Aluminium: 75 HB Mild steel: 120 HB 18–8 (304) stainless steel annealed: 200 HB [3] Quenched and tempered steel wear plate: 400-700 HB Hardened ...
In engineering notation, this is written 40 × 10 6 m. In SI writing style, this may be written 40 Mm (40 megametres). An inch is defined as exactly 25.4 mm. Using scientific notation, this value can be uniformly expressed to any desired precision, from the nearest tenth of a millimeter 2.54 × 10 1 mm to the nearest nanometer 2.540 0000 × 10 ...

The unit, named after Blaise Pascal, is an SI coherent derived unit defined as one newton per square metre (N/m 2). [1] It is also equivalent to 10 barye (10 Ba) in the CGS system. Common multiple units of the pascal are the hectopascal (1 hPa = 100 Pa), which is equal to one millibar , and the kilopascal (1 kPa = 1000 Pa), which is equal to ...
