Revolutions per Second (r/s)

Revolutions per second (r/s) is a unit of angular velocity that measures how many complete rotations or revolutions an object makes in one second. One revolution corresponds to a full 360-degree turn or $2\pi$ radians. This unit is commonly used to describe very fast rotational speeds in machinery, motors, turbines, and other high-speed rotating systems. For example, a motor spinning at 50 r/s completes 50 full rotations every second. Revolutions per second provide a clear and precise measure of rapid rotational motion, useful in physics, engineering, and technology fields where high-speed rotation is involved. It also facilitates easy conversion to other angular velocity units like radians per second or revolutions per minute.

Picometer and Square Picometer – A Short Note

A picometer (symbol: pm) is a metric unit of length equal to:

1 picometer = 10⁻¹² meters

It is used to measure extremely small distances, typically at the atomic and molecular scale. For example, the diameter of a hydrogen atom is about 50–120 picometers. Scientists use picometers in fields like chemistry, nanotechnology, and physics to describe the size of atoms, chemical bonds, and tiny structures.

A square picometer (symbol: pm²) is a unit of area, representing a square with each side one picometer long:

1 pm² = (10⁻¹² m) × (10⁻¹² m) = 10⁻²⁴ m²

This unit is used to express extremely small surface areas, such as the cross-sectional area of atoms or molecules.
