Covers the formulas used in most high-school and early university science and maths courses. Results are rounded to 5 significant figures. Constants used: g = 9.8 m/s², R = 8.314 J/(mol·K), h = 6.626×10⁻³⁴ J·s, N_A = 6.022×10²³ mol⁻¹, F = 96487 C/mol, ε₀ = 8.854×10⁻¹² C²/(N·m²), μ₀ = 4π×10⁻⁷ T·m/A, e = 1.602×10⁻¹⁹ C. Check your course’s values, as some use g = 9.81 or 10 m/s².
