Use this electronics calculation for a first-pass component, converter, signal, motor, or sensor estimate when the stated operating conditions and units match the device data.

Full-scale pressure span (Pa)

Required number input.

Accuracy rating (%FS)

Required number input.

Convert a pressure sensor's accuracy rating as percent of full-scale span into absolute pressure error. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.^[1]

Rated maximum error (Pa)

The resulting rated maximum error returned as a number.

• Sensor output and accuracy calculations depend on excitation, transfer function, reference conditions, loading, calibration, temperature, hysteresis, nonlinearity, bandwidth, cross-sensitivity, and long-term drift. A nominal sensitivity does not establish measurement uncertainty.
• Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Check the result against the current datasheet and worst-case operating corners, then verify the circuit or measurement with simulation and bench testing where failure matters.

• Humidity Sensor Accuracy

  Apply a sensor's specified absolute percent-RH accuracy to a measured relative humidity reading; this is not a confidence interval.

• Magnetometer Resolution

  Estimate one ideal ADC code step in magnetic field from full-scale span and bit resolution; excludes sensor noise.

• ADC LSB Voltage

  Calculate one ideal ADC code width as full-scale input span divided by 2^N. Full-scale span is the high-to-low range, not necessarily the reference voltage for every ADC topology.
