STEP 1: Convert Input(s) to Base Unit

Deoxygenation Constant: 0.23 1 Per Day --> 2.66203703703704E-06 1 Per Second (Check conversion here)
Oxygen Equivalent: 0.21 Milligram per Liter --> 0.00021 Kilogram per Cubic Meter (Check conversion here)
Critical Time: 0.5 Day --> 43200 Second (Check conversion here)
Critical Oxygen Deficit: 0.0003 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

K_R = K_D*L_t*(10^(-K_D*t_c))/D_c --> 2.66203703703704E-06*0.00021*(10^(-2.66203703703704E-06*43200))/0.0003

Evaluating ... ...

K_R = 1.42992129383395E-06

STEP 3: Convert Result to Output's Unit

1.42992129383395E-06 1 Per Second -->0.123545199787253 1 Per Day (Check conversion here)
