Depends on which English system you're talking about. The British yard
did. The gallon used the the USA is the Winchester wine gallon
legalized by Queen Anne in 1707, so it predates the metric system. The
British volume measures were redefined in 1824, however, so the
Imperial gallon and the 20 oz pint in use there date to 1824 which is
AFTER the metric system.
The foot and the pound have their roots in the system of the Roman
Empire. But an old system is not necessarily a better system. The
reason the British reformed their system in 1824, and the reason the
metric system was introduced around 1800 because the historical
measurement units were a huge confusing mess. There were lots of
different pounds, feet, pints, etc, all with different sizes. The
units in one town could be different from the units in another one.
Makes it hard to tell if you're getting what you paid for. And makes
trade hard between different regions.
The Imperial fluid ounce is actually not equal to the US fluid ounce.
So many "pints" have been defined throughout history that to argue that
a particular one is the "real" pint seems futile.
It's a lie. The Imperial gallon was defined to be the space occupied
by 10 lbs of water. The gallon holds 8 pints. This makes the weight
of an imperial pint of water equal to 1.25 lbs.
The USA gallon is defined to be 231 cubic inches and a pint of water in
this system weights a bit more (4%) than a pound.
Unless, of course, you were interested in the USA dry pint which is
about 33.6 cubic inches and hence is 16% larger than the liquid pint.
But you wouldn't measure water in dry pints....
A fluid ounce is a measure of volume (how much space something
occupies). An ounce is a measure of weight (mass). This is a common
source of confusion with the USA system. Switching to the metric
system would at least prevent this from being a source of confusion.
Take something like the weight of paper. When you buy 24 lb bond paper
and then 96 lb card stock does that mean that the card stock was four
times (96/24) the weight of the bond paper? Actually it does not
because in the ridiculous system used here in the USA, card stock is
measured differently than bond paper, so in fact that card stock is
only 92% heavier than the bond paper. The only (reasonable) way to
know what's going on is to look for a metric designation on the paper
in grams per square meter.

In the metric system, a gram is really a unit of mass. Weight is
measured differently (I think the unit is Pascals).

Your mass is the same on earth and on the moon, your weight isn't.
Weight is the force you get when you multiply mass by excelleration,
which is what gravity is.
Speaking of weight, pounds are not consistent!
A pound of feathers is actually HEAVIER than a pound of gold. Gold (precious
metals and some pharmacuticals) is measured in TROY pounds and ounces while
everything else uses the AVIORDUPOIS pound, which is heavier.

Only one quibble. "A pint's a pound the world
around" does not refer to a pint or a pound being
the same anywhere in the world. It is a ditty for
Americans, maybe others that use the same
measures, to remember that a pint of aqueous

about 1 shilling (one-twentieth of a pound) or less. :-)

The 16oz. vs. 20oz. pint issue explains why you will find maintenance
manuals for machines sold on both sides of the Atlantic giving oil or
fuel or coolant capacities as, for example, "5 US pints (4 Imperial
pints)" or "8 Imperial gallons (10 US gallons)". (And now they probably
will have Metric measures as well.)
A fluid ounce is a unit of volume. An ounce is a unit of weight. And
just to complicate matters even further, there are Troy ounces and
Avoirdupois ounces, the former (used for precious metals and jewellery)
being about 10% more than the latter "common" ounce.

Definitely not, but the OP hypothesized an idiot who decided that
America didn't need metric sizes, when in fact metric sizes hadn't
been invented when America started using the sizes we still use.
No single person or even a small group decided we didn't need metric.
In fact a few people decided that we did, but millions of people
didn't want to use it anyhow.
So you got 20 pints for a pound. That's a better deal. Although I
don't know if I could drink that much at one time.
Thanks to you and Adrian.
