If There Were No Derived Quantities, Engineering Wouldn’t Work — Here’s Why

Описание: Fundamental quantities give us the basics — but derived quantities are where engineering actually begins.

In this focused breakdown by Diopter Technologies Limited, we explain what derived quantities are, how they are formed from the seven fundamental quantities, and why concepts like velocity, acceleration, force, pressure, energy, power, and density are impossible without them.

You’ll see how units combine, why dimensional relationships matter, and how derived quantities connect directly to instrumentation, process control, calibration, automation, and electrical systems.

⚙️ What this video clearly explains:

What derived quantities really mean (beyond definitions)

How derived quantities come from length, mass, time, current, temperature, amount, and luminous intensity

Common derived quantities used in engineering and industry

Units explained: m/s, m/s², N, Pa, J, W, kg/m³

Why derived quantities matter in measurement, control, and system design

How instruments measure derived quantities indirectly


This is not rote learning — this is measurement logic, explained the way engineers actually use it.

👉 Watch now and see how derived quantities quietly run every engineered system around you.
