units
edit"HK values are typically in the range from 100 to 1000, when specified in the conventional units of gf·mm−2. The SI unit, pascals, are sometimes used instead: 1 kgf·mm−2 = 9.80665 MPa." is the first unit supposed to be "Kgf·mm−2" instead of "gf·mm−2"? 62.0.44.101 (talk) 11:52, 8 November 2011 (UTC)
- ASTM 384 contains the following
- "1.2 This test method covers microindentation tests made with Knoop and Vickers indenters under test forces in the range from 9.8 × 10-3 to 9.8 N (1 to 1000 gf)."
- so I would assume that gf·mm−2 is correct 87.191.38.2 (talk) 07:58, 1 December 2022 (UTC)
