Atomic weights are used to convert the mass of a sample into the number of moles of the element in the sample and vice versa. Four examples are provided for practice.

In this animated and interactive object, learners follow two rules to write unit conversion fractions.

Students view the formulas to be used to convert a series impedance to a parallel impedance.

Learners observe animations showing how data is converted between serial and parallel flow.

Students view the formulas to be used to convert a parallel impedance to a series impedance.

The conversion from rectangular to polar mode phase angle in radians is demonstrated in Excel.

Students read an introduction to the transconductance amplifier. They also view formulas for voltage-to-current conversion, closed-loop input, and output impedance. An example of how R1 controls the conversion factor is given.

Learners read how to convert complex numbers to their polar equivalent in Excel.

Students read how to use the DEGREES() function to convert radians to degrees.

Learners convert a number from standard form to engineering notation.

In this learning activity you'll review the hexadecimal numbering system.

In this learning activity you'll explore the IPv4 IP address scheme and the planned conversion to IPv6.

The current-to-voltage conversion of the transresistance amplifier is examined. The formulas for output voltage and impedance are defined and an example ties the concepts together.

Learners read how inches of water column is used as a unit of pressure measurement. Practical applications and a conversion formula to psi are included.

Learners follow the steps for reducing all of the elements of a complex circuit to a single current source and a single source resistance to create a simple circuit. Several examples are given for dc circuits. The conversion between Thevenin and Norton is also presented.

In this animated activity, learners examine the conversion of electrical energy into an electrostatic charge within the dielectric material of a capacitor.
