Advanced Utility Grid — Science & Utility Modules
Part A — Science Tools (Physics, Chemistry, Electric)
Physics — Frequency (Hertz) Converter
How to use / Benefits / FAQ
Use: Enter frequency and choose unit → Convert. Benefit: Instant conversions for audio, radio, and electronics. FAQ: 1 Hz = 1 cycle/sec; kHz=1e3 Hz.
Physics — Speed Converter (ft/s ↔ mph ↔ m/s)
How to use / Benefits / FAQ
Use: Enter speed & unit → convert. Benefit: helpful for physics problems, vehicle speed checks, ballistics. FAQ: 1 ft/s = 0.3048 m/s; mph->m/s uses 0.44704 factor.
Physics — Acceleration (Gal)
How to use / Benefits / FAQ
Use: Enter Gal value. Benefit: geophysics & seismology uses Gal (1 Gal = 0.01 m/s²). FAQ: 980 Gal ≈ 9.8 m/s² = 1 g.
Chemistry — Density Converter (g/cm³ ↔ kg/m³)
How to use / Benefits / FAQ
Use: Useful for lab calculations, materials. 1 g/cm³ = 1000 kg/m³. FAQ: Use temperature-corrected densities for precision.
Chemistry — Molar Mass Helper (g/mol)
How to use / Benefits / FAQ
Use: Enter molecular formula (simple, no parentheses) → estimate molar mass. Benefit: quick checks for stoichiometry. FAQ: For complex formulas use chemistry libraries — this is a basic helper.
Chemistry — Stokes Unit Converter (Stokes ↔ m²/s)
How to use / Benefits / FAQ
Use: 1 Stokes = 1e-4 m²/s. Benefit: fluids & colloids calculations. FAQ: SI unit is m²/s (kinematic viscosity).
Chemistry — Amount (moles) Calculator
How to use / Benefits / FAQ
Use: n = mass / M. Benefit: stoichiometry & lab prep. FAQ: Ensure same mass units.
Electric — Ohm’s Law & Power Calculator
How to use / Benefits / FAQ
Use: provide any two → compute the rest using V=IR, P=VI. Benefit: electronics debugging & quick checks. FAQ: Ensure units match; P=V*I; R=V/I.
Part B — Utility Tools (Math, Time, Health)
Math — Quadratic Solver
How to use / Benefits / FAQ
Use: input coefficients → get roots. Benefit: students & quick algebra checks. FAQ: Handles complex roots.
Math — Factorial & Permutations
How to use / Benefits / FAQ
Use: factorial & nPr/nCr logic. Benefit: combinatorics & probability quick checks. FAQ: n up to 20 is safe for JS integer math; big integers not supported here.
Time — Unit Converter (s, min, hr, day)
How to use / Benefits / FAQ
Use: copy value→select unit→convert. Benefit: scheduling, logs, metrics. FAQ: uses exact SI conversions (1 day=86400s).
Health — BMI & BMR Calculator
How to use / Benefits / FAQ
Use: get BMI category and estimated BMR (Mifflin-St Jeor). Benefit: quick health checks & calorie planning. FAQ: consult healthcare for diagnosis.
Utility — Age Calculator (Add to main tools)
How to use / Benefits / FAQ
Note: This small module is ideal to embed within your main ‘Calculator Tools’ page — it’s compact and commonly used.
