PHARMAEDGES QUALITY TOOLKIT
Choose the right calculator for the task.
Basic formulas stay separate from more advanced pharmaceutical and manufacturing calculators, so users can move directly to the right level of analysis.
QUICK & TRANSPARENT
Basic calculators
Focused calculations with visible formulas, unit guidance, input validation and immediately readable results.
Dilution Calculator
C₁V₁ = C₂V₂
Molarity Calculator
M = moles ÷ litres
Normality Calculator
N = equivalents ÷ litres
W/V Calculator – Weight/Volume Percentage
% w/v = grams ÷ mL × 100
Percentage v/v Calculator
% v/v = solute mL ÷ solution mL × 100
PPM Calculator
mg/L = solute mg ÷ solution L; ppm assumes density 1 kg/L
Assay Calculator
Assay % = sample response ÷ standard response × potency (%)
Percentage RSD Calculator
%RSD = standard deviation ÷ mean × 100
PHARMA & OPERATIONS ANALYTICS
Advanced calculators
Higher-value calculators for risk scoring, capability analysis, production metrics, inventory planning and pharmaceutical preparation math.
FMEA Quality Risk Assessment
RPN = severity x probability x detectability
Open calculator →Change Control Risk Assessment
Weighted impact and readiness metrics
Open calculator →Process Capability Analyzer
Cp = (USL - LSL) / 6sigma; Cpk = min[(USL - mean), (mean - LSL)] / 3sigma
Open calculator →Batch Yield Calculator
Yield % = actual output / theoretical output x 100
Open calculator →Buffer Preparation Calculator
Mass = molarity x molecular weight x volume
Open calculator →OEE Calculator
OEE % = availability (%) x performance (%) x quality (%) / 10,000
