Thanks for the correction. I simply cut and pasted the article without
reading it carefully. I will watch the 'Geelong Advertiser' more
closely in future.

mindset where the unit megalitre is used for capacities

Dear Martin and Aaron,
I see two issues:
1 You need to be more specific if you use BTUs as these vary with
temperature.
2 Avoiding the use of the single coherent SI unit for energy, joule,
means that you have difficulty comparing the energy used in different
industries. See
I agree with your second issue, and you certainly want your fuel supplier using
the same BTU.
On the first issue, there is little doubt that the steam industry wouold use

Dear Pat,
Let me guess. Before metrication, they used acre-feet (at least we do in the
US).
1 acre-foot = 43560 ft³ x (0.3048 m/ft)³ = 1233.5 m³
or 1.2335 ML or 1.2335 dam³. So it is an almost familiar size unit.
The agricultural section of SAE recommends the cubic dekameter wherever
I understand that the US oil industry uses barrels per acre-foot (where the
foot refers to the thickness of the oil-bearing strata). If this is
reduced to rational units, we get a dimensionless number which can be
expressed as a percentage!

I had never heard of that usage, but it is apparently true. If I append the
word oil to a Google search on acre foot, I only get 7.6% as many hits. But
many relate to barrels per acre-foot. Several calculate the barrels of rock
in an acre-foot and calculate porosity.
Without the word oil,

Would you say that SAE is metric now where once it was pre-metric? Now, what
do you think of when you see wrench sets described as Metric or SAE, implying
that SAE sponsored tools are not metric?

If the metric board were reconvened, I'd want to see some changes:

disproportionate compared to the other interests. Four less members might make
it work better.
*All members should be advocates for metrication from
I wouldn't know where to begin. But in your estimates did you factor in the
cost of training and lost time and productivity due to resistance?
My point is, why should a company bother to metricate its production and staff
when it can have the products made in metric elsewhere with no
The SAE has a current metric practice guide, SAE TSB003. It was reassigned to
the Technical Standards Board in 1992. It was previously known as J916, and
was first issued 1965-06.

While I agree that would be better, the American West manages water rights in

of water elevation in feet at each dam, release in cubic feet per second and

Dear John,
You are right. Acre-feet was the common measure for water in
Australia. This unit was especially useful for irrigation where it
made some sense when we used acres to measure land surface areas. Acre
feet and acres are no longer used here for any official purpose

Your reply made me think that someone opposed to metric usage by SAE could
simply refer to a pre-metric version of their standard to justify using SAE as
a supporter for a non-metric reference.
In the example I gave previously, it was tools that sold sold with the claim
that SAE tools are inch
Since an acre-foot is about 1200 m^3, then 75 000 000 x 1200 = 90 000 000 000
m^3 = 90 km^3.
In other words, an acre-foot is about 80 % as large as a cubic dekameter.

SAE maintains separate standards in inch units and metric (Ibelieve ASME does
the same). The standards for inch bolts, threads, wrenches are maintained and
periodically reaffirmed. Mostly they are SOLD for $50; I doubt they'll be
disavowed.
But SAE has separate metric standards for bolts,
That's true, but the law is written in acre-feet. For puposes of legal
compliance, it is usually desirable to use the units mandated by law and not
throw in conversions.
It is another example of law in Customary units that needs to be fixed if we
ever have a REAL national plan to metricate.

As silly as some of those names may seem, they should allow for easy conversion

Who can easily convert acre feet to gallons or cubic feet?

Tire mechanics are not the brightest bulbs in the pack
H, well they'd know that the marking on the tyre is not the correct figure
to inflate the tyre to. You inflate the tyre to what the car manufacturer

Not the brightest.Quite.

That is correct. In the US, it is specified on a door sticker as well as the
owner's manual. My Edge would like 240 kPa / 35 PSI all around. (The metric
is in the primary position.)
I did not squat down to read the tire. Black on black is hard to read anyway.
