Formulae Measurements

Vocabulary flashcards covering measurement formulas, period, frequency, and time conversions.

Vemier Caliper measurement

The reading is calculated using the formula $Ms + Vs$, for example, $12\,\text{mm} + 0.7\,\text{mm} = 12.7\,\text{mm}$.

Macrometer screw gauge reading

Calculated using the formula $Ms + \text{Thimble scale reading} \times 0.01$, with an example given as $7.5 + 5 \times 0.01$.

Peaed (Period)

The time taken per oscillation, calculated as $\frac{\text{time baken}}{\text{number of oscillations}}$, such as $\frac{20}{10} = 2\,\text{seconds per oscillation}$.

Frequency

Calculated using the formula $F = \frac{1}{T}$, for example, $\frac{1}{2} = 0.5\,\text{Herbz}$.

Time calculation formula

Calculated as $\text{Min} \times 60\,\text{s} + \text{Seconds} + \frac{\text{Mini Seconds}}{10/100/1000}$, illustrated by the example $3 \times 60 + 175 + \frac{81}{100} = 180 + 175 + 0.81 = 355.815$.
