But in practice what we do a differential counts, how many per unit flux or other per unit magnitude.

So, spectral energy distribution which is the shape describes the spectrum of an object is defined to be energy per unit time per unit second per unit for frequency or wavelength and we never observe that, that's a differential unit.

So here, you have a lot of those particles per unit space and here you have very few of those particles per unit space.

Those are lines of equal power consumption per unit area, which I measure in watts per square meter.

OK, what is the quantity per day going to be produced, if that's the price?

One unit that is often used is jansky which was introduced by radio astronomers and it's 10 ( 23) ergs per second per centimeter square per hertz.

Quantity supplied...

So, for example, the middle line there, 0.1 watts per square meter, is the energy consumption per unit area of Saudi Arabia,

This quantity minus 14x is this quantity right there.

That this quantity is greater than this quantity and that this quantity's greater than that quantity.

If someone just said 5 kilometers per hour ... ... they're giving you a speed ... ... or rate ... ... or scalar quantity.

lensed per unit time is giving you effectively an optical depth due to gravitational microlensing.

When we say rate, we mean the amount of energy transferred per unit of time.

Just to be clear, sometimes angular velocity is actually measured in revolutions per second but the SI unit is in radians per second

That is if we can measure the total luminosity, but, we usually measure specific flux, which is power per unit wavelength or unit frequency.

Fossil fuel usage is down 60 percent per unit of production, due to efficiencies in renewables.

Acceleration is a vector quantity and Force is a vector quantity

Quantity in a set

lower the quantity demanded.

But the very simple idea is, how much of that particle do you have per unit space?

They all have a small power per unit area, and we have to live with that fact.

When we're talking about a particular quantity we'll be careful to say quantity

If we talk about an actual quantity, we should say the quantity demanded.

Impossible unit conversion based on unit types

I put quantity after quality.

I prefer quality to quantity.

So this first quantity here,

You're changing the quantity demanded.

Per second per megaparsec.

Concentrating solar power in deserts delivers larger powers per unit area, because you don't have the problem of clouds.
