Speaking of barleycorns reminds me that one can have a lot of fun with
units. My favorite combination has components
atmosphere = 101,325 newton/m^2
yard = 0.9144 m
barn = 1 x 10^(-28) m^2
Combining these we get the

Yes, but we really never translate it - from the French! Coup de grace
Now I am sure it makes sense. But if I were to say coup de grace
I would be accused of suffering of francophilia.
Dear Rod
I am glad you've diverted from the accurate vs. precise
issue. You know, to me this is so confusing I though I could
help myself bringing the terms into Portuguese. You know
what? Things only got worse.

I think Mike Shaw stated the matter for good using fromerly cited examples

Strictly speaking accuracy and precision are sort of independent. If your
mean (average) shot is on the target then you are accurate even if you
never hit the target precisely. Your shots may be off

If the 10 holes in the target are tightly grouped, but near

If they are loosely grouped evenly around the bull, you are
accurate, but not precise.

John,
Accurate and precise are relative terms; they are meaningful only in
context. I would think that one could have a ring sundial that was precise
relative to other ring dials, although not precise relative to large,
finely-divided dials. I agree that in general large dials with small

Hello John,
Normally precision of a measurement refers to the repeatability and
accuracy to the absolute closeness to the true value. However, after
studying Heisenberg I gave up caring! I remember the distinction

On the other hand, a heliochronometer would HAVE to be precise and

it is well-made and has small (1 min?) time divisions. Right?
How about a misaligned heliochronometer (ie, set for the

My distant history tells me this:
Precision usually means the number of significant figures used to report a
measurement.
Accuracy usually means how close your reported measurement is to the truth.
