Congress passed 6 years ago a law that will require the use of metric
horses in measurements of horsepower. A metric horse is 0.84 the
size of an American horse. This will increase the horsepower of all
American engines by 16 percent.
There is a bill before Congress now to also change to metric power.
Metric power is 90% of English power. If that law is passed, one
horsepower will be 0.84 x 0.90 times what it was. This will also
increase horsepower and will save gasoline.
Americans don't speak English; they use 'Amurrican' with all kinds of
letters left out; e.g. color instead of colour, humor instead of
humour! Tire instead of tyre. And weird abbreviations such as
'sox' (instead of socks, which is itself a shortening of stockings).
And how do Americans spell if it is a single sock? Also 'foto' from
'photo', itself a total shortening of the original (French)
'Photogravure' ; which is the way my grandfather, with his glass plate
camera would have pronounced and spelt it!
The US gallon (rarely used elsewhere by the way) is approximately 80%
the size of the Imperial gallon. Consequently it contains fewer
litres! One of the few cases where anything 'In America', including
Texas, is smaller than elsewhere?
Although somebody referred to George W. as "Shrub"!
Also some oddities of calculation?
While agreeing that adoption of the metric system has led to some very
odd numbers, especially to someone brought up the other way; sheets of
plywood still arrive 4 by 8 feet (48 by 96 inches), lumber as two by
fours, although they never are, the numbers referring to the rough
lumber dimension before planing and now called something along lines
of 100 millimetres by 50 mm. or something? Carpet rolls still seem be
in 12 foot widths?
Oh and while we are on the subject; it is more correct to spell it as
"metres" not "meters".
'Meters' are things that measure other things; as in 'Voltmeter',
'Ammeter', "Electricity meter', 'Test-meter' or 'Watt-meter'; OK?
But have sympathy for those of us please, who were brought up learning
and using 'Pounds, shillings and pence' along with 'Rods, poles,
chains and perches, for land, measurements! (Encountered one world
location where land is still measured, advertised and sold in Perches
Then there are/were metric tonnes, nautical miles, knots per hour,
guineas, half crowns, florins, ha'pennies (half pennies), and now
Euros (a sort of European dollar if you get the drift?). And one could
go on to bushels, bales of cotton, pounds of coffee and housing and
building products measured in square metres. There are roughly ten
square feet in a metre squared, as it is expressed.
Oh and by the way in Canada we measure vehicle fuel consumption in
litres per 100 kilometres. Although some hold outs still, think in
miles per gallon; same miles but Canadian Imperial gallons. So we get
more miles per gallon (Oops, sorry; that's fewer litres per 100
kilometres!) in Canada. Got that, eh?
You say tomato? We say tomato? (Gee I alwys thought there was an 'e'
in that word somewhere; guess I was wrong)?
Any way cousins; have fun with our 'common' language, we do. Although
some of us even use French first; and because a significant proportion
of our population has that background and culture, it enriches us.
Maybe Spanish will do so also?
Although these days maybe smarter to learn Mandarin Chinese or Indian
With our warm regards.
In the 18th Century, James Watt invented the HP. He defined it in terms
of feet, pounds, and minutes. Before the Metric System, nobody knew
exactly what feet, pounds, and minutes were; but the HP was a good
Late in the 19th Century, the Germans defined the PS, which was a
horsepower slightly adjusted to be easier to calculate with meters and
kilograms. One PS was .986 HP.
That's what was meant by the Metric Horsepower. Countries all over the
continent adopted it under different names. Nobody cared if a 5 PS
engine was only 4.93 HP. They loved the easier calculations. It was
never part of the Metric System and Europe outlawed it in 1992.
The difference in how HP is measured can matter a lot more than the
difference between HP and PS. I bought a 1970 BMW motorcycle rated at
57 SAE HP and 50 brake HP. The former was measured at the crankshaft.
The latter was measured at the rear wheel.
You inspired me to look it up. Thanks. I think the Japanese still use
metric horsepower. The modern unit is kilowatts.
I believe so, given in RPMs. Brake HP was reduced by what was lost in
the transmission and ring-and-pinion. Maybe it was also reduced by the
friction of distorting the back tire. It's possible that the SAE
standard allowed more liberty with the exhaust system and the alternator.
