Education

Wright–Fisher Population Drift & Allele Frequency Tutor

Simulate Wright–Fisher genetic drift across many replicate populations with mutation and selection. Visualize drift trajectories, the final-frequency distribution, heterozygosity decay Hₜ = H₀(1−1/2Nₑ)ᵗ, and run a Hardy–Weinberg chi-square test.

Utilities

ISO Week Number and Fiscal Quarter Anchor Finder

Convert any date to ISO 8601 week number, day-of-year, Julian Day, and fiscal-quarter boundaries (4-4-5, 4-5-4, 13-week, or standard).

Network

Wi-Fi Channel Overlap Planner

Plan 2.4, 5, and 6 GHz Wi-Fi channels from measured AP channels, widths, and RSSI, with overlap, DFS, and PSC warnings.

Text Processing

IPA Phonetic Transcription and Pronunciation Coach

Turn English words into teaching-oriented US/UK IPA, color-coded phonemes, articulation cues, and minimal-pair drills.

Math & Numbers

Weir Flow Calculator (Rectangular & V-Notch Weirs)

Compute the discharge over a sharp-crested thin-plate weir. Rectangular (suppressed, no side contraction): Q = (2/3)·C_d·√(2g)·b·H^1.5. V-notch (triangular): Q = (8/15)·C_d·√(2g)·tan(θ/2)·H^2.5. b is the crest width, H the head over the crest (or over the vertex for a V-notch), θ the notch angle. If C_d is left blank it defaults to 0.611 for rectangular weirs (Rehbock/Francis typical value) and 0.58 for V-notch weirs. Crest width in m/cm, head in m/cm/mm; output in m³/s, L/s, L/min and m³/h.

Math & Numbers

RLC Impedance & Phase Angle Calculator

Compute complex impedance, magnitude |Z| and phase angle φ for series or parallel RLC circuits: X_L=2πfL, X_C=1/(2πfC), |Z|=√(R²+X²), φ=atan2(X,R). Supports any subset of R/L/C and an optional linear frequency sweep.

Media

Image Bit Depth to PNG Converter

Convert images to exact monochrome, indexed, grayscale, RGB, or RGBA PNG bit depths with verified output.

Math & Numbers

Wedge Angle Force Calculator

Calculate the force-amplification ratio and self-locking condition of a wedge mechanism. Ideal M = 1/tan(α), with friction M = 1/tan(α+ρ) where ρ = arctan(μ). Self-locking when α ≤ ρ (i.e. tan(α) ≤ μ).

Finance

Investment Calculator

Project investment growth with initial principal plus monthly contributions and compound interest. Supports compounding frequency, inflation-adjusted real value, and yearly contribution escalation, with a yearly breakdown table and nominal vs real balance curves.

Media

Image to WEBP Batch Converter

Convert up to 20 uploaded images, or images inside a ZIP archive, into WebP files packaged as a ZIP

Utilities

Interior Paint Coverage Estimator

Estimate how many buckets of interior paint you need from room dimensions, doors/windows, coats, paint coverage, and bucket size — rounded up to whole buckets, with optional primer and waste factor.

Utilities

IUPAC Organic Naming Tool

Parse SMILES, detect the senior functional group, find the longest carbon chain, and emit a teaching-oriented IUPAC name with E/Z and R/S hints.
