Interactive Multi-Variable Formulas
Animal Injection Volume Calculator
Volume (mL) = [Dose (mg/kg) × Body Weight (kg)] / Concentration (mg/mL)
Calculate exact injection dose volume (mL) for mouse, rat, or rodent in vivo xenograft and pharmacokinetic studies.
Animal to Human Equivalent Dose (HED)
HED (mg/kg) = Animal Dose (mg/kg) × [Km(animal) / Km(human)]
Convert animal experimental doses (mouse, rat, dog, monkey) to Human Equivalent Dose (HED) based on Body Surface Area (BSA) normalization.
Body Surface Area (Mosteller Formula)
BSA (m²) = √ [ (Height (cm) × Weight (kg)) / 3600 ]
Calculate physiological Body Surface Area (BSA) using the widely adopted Mosteller equation.
Calvert Carboplatin AUC Dosing
Dose (mg) = Target AUC (mg·min/mL) × [ GFR (mL/min) + 25 ]
Calculate carboplatin individual dose targeting a specific area under the plasma concentration-time curve (AUC).
Solution Dilution (C1V1 = C2V2)
Concentration₁ × Volume₁ = Concentration₂ × Volume₂
Calculate the required stock volume or final concentration when diluting laboratory chemical buffers, reagents, and drug solutions.
Reagent Molarity & Mass Calculator
Mass (g) = Molarity (M) × Volume (L) × Molecular Weight (g/mol)
Determine the exact mass in grams to weigh on an analytical balance when preparing molar chemical and biochemical solutions.
Electric Power Law (P = V × I)
Power (Watts) = Voltage (Volts) × Current (Amperes)
Calculate electrical power, voltage, current, or resistance in direct current (DC) or resistive alternating current (AC) circuits.
Ohm’s Law (V = I × R)
Voltage (Volts) = Current (Amperes) × Resistance (Ohms)
Calculate voltage, current, or electrical resistance across a conductor.
Kinetic Energy (KE = ½ m v²)
Kinetic Energy (Joules) = ½ × Mass (kg) × [Velocity (m/s)]²
Calculate the kinetic energy possessed by an object due to its motion.
Speed, Distance & Time (d = v × t)
Distance = Speed × Time
Calculate travel duration, distance covered, or required average speed.
