Packs
Packs add nodes and functions for a domain. Geometry and the Excel timesavers are on out of the box; turn the rest on under Settings ▸ Packs. A pack's functions also work in formulas, and its units show up in the Format Controller.
Everyday
Geometry
Geometric helpers: hypotenuse, the any-three-parts Triangle Solver, circles and arcs, solids.
Common Excel Timesavers
Conveniences that aren't single Excel functions: weighted stats, list utilities, percent change, CAGR, text cleanup, date helpers, time zones, Spell Number, QR codes.
Health & Fitness
BMI, BSA, BMR and TDEE, body fat, heart-rate zones, VO₂max, ideal weight, creatinine clearance. Metric inputs. Estimates, not medical advice.
Sets & Membership
List membership and counting: Is In (the ISNUMBER(MATCH()) idiom), Tally (value counts) and COUNT DISTINCT. Join's semi and anti modes cover tables.
Analysis
Scientific Computing
FFT spectrum, smoothing, peak finding, convolution, ODE integration, linear solve, eigenvalues, polynomial roots, distribution fitting, seasonal decomposition.
Data Science
K-Means, PCA and logistic regression; Kruskal-Wallis, Mann-Whitney, Wilcoxon, Fisher exact and Kolmogorov-Smirnov tests.
Science & Engineering
Electricity & Circuits
Ohm's law and power, dividers, reactance and resonance, RC and RL transients, decibels, resistor color codes, E-series values, AWG wire properties. SI units.
Electromagnetism
Coulomb, Lorentz, Faraday, capacitance and inductance from geometry, skin depth, spectrum bands, CODATA constants. Builds on Electricity & Circuits.
Fluid Mechanics
Reynolds, Colebrook and Swamee–Jain friction, Darcy–Weisbach and Hazen–Williams losses, Bernoulli, pumps, settling, drag, sound speed. SI units.
Thermodynamics & Air
Ideal gas, conduction, convection, radiation, R and U values, dew point, wet bulb, heat index, wind chill, standard atmosphere, vapor pressure.
Earth & Sky
Great-circle distance and bearing, gravity by latitude, horizon, Kepler orbits, escape velocity, NOAA sun position and rise/set, moon phase.
Chemistry Basics
Periodic table, molar mass from a formula (hydrates too), moles, molarity, dilution, pH, Nernst, Arrhenius, Gibbs, Beer–Lambert, decay.
