Units and Conversions

From this App you can learn :

Use a scientific notation, powers of ten, while writing numbers of very large and very small sizes compactly and memorize the SI prefixes of powers of ten.
Scale the derived units by applying decimal multiplying factors and convert the magnitudes of units into different systems of units by using conversion factors.
Classify the errors that occur during experiments, avoid and rectify the errors while doing an experiment.
Cross check whether you are accurate or precise by using your experimental data.
Measure the uncertainity in the experimental value.
Round off the calculated value by using significant figures.
Recognize the significance of physical constants such as Planck's constant (h), Boltzmann constant (k) etc.
