STEP 1: Convert Input(s) to Base Unit
Net Ultimate BC: 87 Kilonewton per Square Meter --> 87000 Pascal (Check conversion here)
Cohesion in Soil as Kilopascal: 1.27 Kilopascal --> 1270 Pascal (Check conversion here)
Bearing Capacity Factor dependent on Cohesion: 9 --> No Conversion Required
Effective Surcharge in KiloPascal: 45.9 Kilonewton per Square Meter --> 45900 Pascal (Check conversion here)
Bearing Capacity Factor dependent on Surcharge: 2.01 --> No Conversion Required
Unit Weight of Soil: 18 Kilonewton per Cubic Meter --> 18000 Newton per Cubic Meter (Check conversion here)
Bearing Capacity Factor dependent on Unit Weight: 1.6 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
B = (qnu-((C*Nc)+(σs*(Nq-1))))/(0.5*γ*Nγ) --> (87000-((1270*9)+(45900*(2.01-1))))/(0.5*18000*1.6)
