Units and Measurements

Converts the numerical magnitude of a physical quantity from one system of units to another.

Expresses experimental uncertainty as a fractional ratio or percentage of the true mean value.

Gives the maximum absolute error when two independent measured quantities are added or subtracted.

Calculates the maximum relative error for a physical quantity formed by products, quotients, and powers.

Gives the smallest measurable interval of vernier callipers where n vernier divisions equal (n - 1) main scale divisions.

Determines the corrected measurement using the main scale reading and the coincident vernier division n.

Gives the smallest length measurable by a micrometer screw gauge.

Gives the true measured value by combining linear scale reading, circular scale coincidence, and zero error correction.
