GUIDE TO CONE PENETRATION TESTING - Novo …
GUIDE TO. cone PENETRATION . TESTING . Engineering Units Multiples Micro ( ) = 10-6. Milli (m) = 10-3. Kilo (k) = 10+3. Mega (M) = 10+6. Imperial Units SI Units Length feet (ft) meter (m). Area square feet (ft2) square meter (m2). Force pounds (p) Newton (N). 2. Pressure/Stress pounds/foot (psf) Pascal (Pa) = (N/m2). Multiple Units Length inches (in) millimeter (mm). Area square feet (ft2) square millimeter (mm2). Force ton (t) kilonewton (kN). 2 2. Pressure/Stress pounds/inch (psi) kilonewton/meter kPa). tons/foot2 (tsf) meganewton/meter2 (MPa). Conversion Factors Force: 1 ton = kN. 1 kg = N. Pressure/Stress 1kg/cm2 = 100 kPa = 100 kN/m2 = 1 bar 1 tsf = 96 kPa (~100 kPa = MPa). 1 t/m2 ~ 10 kPa psi = 100 kPa foot of water = 1 psi 1 meter of water = 10 kPa Derived Values from CPT. Friction ratio: Rf = (fs/qt) x 100%.
