Introductory Physics
Familiarity with basic mechanics and energy concepts provides context for engineering-level analysis.
Measurement Calculators
Uncertainty Propagation Calculator
RSS uncertainty propagation for sum, product, quotient, power, or custom formula. Shows contribution of each measurement to total uncertainty.
Sensor Calibration Calculator
Best-fit sensitivity, linearity error, hysteresis, accuracy, and precision from calibration data pairs. Calibration curve chart with up/down sweep.
SNR Calculator
Signal-to-noise ratio in dB from signal/noise power or amplitude. Dynamic range, noise floor, and conversion between power and amplitude SNR.
Strain Gauge Calculator
Quarter, half, and full Wheatstone bridge configurations. Compute strain ε = ΔV/(V×GF×n) and stress from gauge factor and bridge voltages.
Thermocouple Reference Calculator
Types J, K, T, E, R, S, N. Temperature → voltage or voltage → temperature with cold junction compensation and type comparison chart.
Measurement Resolution Calculator
ADC bits and voltage range → resolution (LSB), quantization error, dynamic range (dB), ENOB. ENOB from measured SINAD. Bit-resolution comparison.
