Science & Education

Mass-Energy Equivalence Calculator

E = mc² both ways: mass to rest energy (J, kWh, eV-scale, TNT) and energy to mass (kg, g, u, electron masses).

Science & Education

de Broglie Wavelength Calculator

Matter-wave λ = h/p via particle & speed (γmv optional), direct momentum, or electron voltage (relativistic + h/√(2mE) comparison). Units from m to fm/Å with wavelength scale.

Science & Education

Electron Configuration Calculator

Look up electron configurations, shell distributions, valence electrons, and orbital diagrams by element symbol or atomic number

Science & Education

Conductivity Cell Constant Calculator

K = κ/G and κ = K·G with unit selectors for κ, G and K — calibrate the cell or convert a reading into conductivity.

Science & Education

Compton Scattering Calculator

Δλ = (h/m_e·c)(1 − cos θ) for X-ray photons: Compton wavelength, shifted wavelength/energy, recoil electron energy and angle, 0°/180° edge cases.

Science & Education

Codon to Amino Acid Translator

Translate a DNA or mRNA sequence into protein using the standard genetic code. Scans all 6 reading frames (forward and reverse complement), marks start (AUG) and stop codons, identifies the longest open reading frames (ORFs), and shows the amino-acid composition with color-coded residue types. Supports T→U normalisation and reverse-complement translation.

Science & Education

Battery Capacity Calculator

C = I·t both ways — runtime from capacity or capacity from runtime — with optional voltage for Wh and W.

Science & Education

Beer-Lambert Law Calculator

A = ε·c·l both ways, with T = 10⁻ᴬ, %T, unit selectors, and the 0.05–1.0 working-range check.
