Acceleration

Acceleration is the change in velocity over time.

Angle

Angles express rotation.

Area

Area quantifies how much surface a shape covers.

Bandwidth

Bandwidth measures how quickly data moves across a network link.

Capacitance

Capacitance is stored electric charge per volt.

Data

Bits store binary 0s and 1s, and a byte equals 8 bits.

Density

Density is mass per unit volume.

Electric Current

Electric current is the flow of electric charge through a conductor.

Energy

Energy is the capacity to do work.

Flow Rate

Volumetric flow indicates how much fluid moves each interval.

Force

Force is a push or pull on an object.

Frequency

Frequency counts how many cycles occur each second.

Fuel Consumption

Fuel economy describes how far a vehicle travels per amount of fuel.

Heat Flux

Heat flux measures power passing through a surface area.

Illuminance

Illuminance is the light falling onto a surface.

Inductance

Inductance measures how a conductor resists changes in current by inducing voltage.

Length

Length measures the distance between two points.

Luminance

Luminance describes light emitted or reflected from a surface area.

Magnetic Flux Density

Magnetic flux density indicates magnetic field strength.

Power

Power is the rate of doing work.

Pressure

Pressure is force applied over an area.

Radiation Dose

Radiation dose measures energy absorbed by tissue.

Resistance

Electrical resistance opposes current flow.

Speed

Speed measures distance traveled per unit time.

Temperature

Temperature reflects thermal energy.

Time

Time tracks duration based on the second as the SI unit.

Torque

Torque is a twisting force around an axis.

Voltage

Voltage is electric potential difference that drives current.

Volume

Volume measures three-dimensional space for liquids or containers.

Wavelength

Wavelength is the physical length of one wave cycle.

Weight

Weight (mass) expresses how much matter something contains and is measured the same way regardless of local gravity.
