Science & Education

Molar Conductivity Calculator

Λm = κ/c in S·cm²/mol and S·m²/mol, with optional α = Λm/Λ°m and Ka for weak electrolytes.

Math & Numbers

Modular Inverse Calculator (Extended Euclidean Algorithm)

a⁻¹ mod m via extended Euclid with Bézout coefficients, an optional step table, and an a × a⁻¹ ≡ 1 (mod m) verification; RSA-sized inputs supported.

Math & Numbers

Modular Arithmetic Calculator (Add / Subtract / Multiply / Inverse / Power)

Exact BigInt modular arithmetic for values up to 10¹⁸: (a ± b) mod m, (a × b) mod m, a⁻¹ mod m via extended Euclid, and aᵇ mod m via fast exponentiation.

Education

Molar Extinction Coefficient & Beer-Lambert (A = ε·c·l)

Solve A, ε, c or l from the Beer-Lambert law A = ε·c·l, with M/mM/µM/nM and cm/mm unit support.

Health

Molar ↔ Mass Concentration Converter (mM × MW)

Convert molar ↔ mass concentration (mmol/L, µmol/L, mol/L ↔ g/L, mg/L, mg/mL, mg/dL, µg/mL) from a molecular weight; returns every unit at once. Not medical advice.

Education

Multiplicity of Infection (MOI) Calculator

MOI from titer/volume/cells or the virus volume for a target MOI, with Poisson % infected. Educational use only.

Education

DNA Molar Concentration Calculator (µg/mL → nM)

Mass-to-molar DNA conversion: nM = (µg/mL × 10⁶)/(Da-per-bp × bp) with 650 Da/bp dsDNA and 330 Da/nt ssDNA, plus µM, pmol/µL, total pmol, and molecules/µL via Avogadro. Warns about the µM-vs-nM 1000× slip. NEB NEBioCalculator / Promega BioMath derived. Educational use only.

Math & Numbers

Moment of Force Converter (N·m / dyn·cm / lbf·ft / kgf·m)

Convert moment of force (torque) between newton-metre (N·m, SI base), dyne-centimetre (dyn·cm, CGS = 10⁻⁷ N·m), pound-foot (lbf·ft = 1.3558179483314004 N·m), and kilogram-force-metre (kgf·m = 9.80665 N·m). Each factor is the exact product of the matching force factor and length factor. Converts via N·m to the target unit and lists all four equivalents. Reference: wheel-nut tightening torque ≈ 100 N·m, passenger-car engine peak torque ≈ 250 N·m.

Math & Numbers

Motor Efficiency Calculator (η = P_out / P_in)

Compute motor efficiency η = P_out / P_in. Supports electrical input (single-phase U·I·cosφ or three-phase √3·U·I·cosφ) or direct P_in; output power can be derived from a loss breakdown (copper+iron+rotor copper+mechanical+stray) or supplied directly.

Math & Numbers

Three-Phase Induction Motor Slip Calculator

Compute three-phase induction motor slip: synchronous speed n_s = 60·f/p and slip s = (n_s − n)/n_s. Supports slip-from-speed and speed-from-slip modes; automatically flags generator mode (s < 0).

Math & Numbers

Induction Motor Torque-Speed Characteristic (Kloss)

Build the torque-speed curve of a three-phase induction motor using the Kloss equation T/T_max = 2/(s/s_max + s_max/s). Returns rated torque, breakdown (max) torque, starting torque, breakdown slip, and a sampled T-n curve with configurable point count.
