I've heard 'an ounce per minute',(clip)

An ounce per minute is 20 oz per 20 min, which is pretty close to a liter
per 20 min. This is not an exact science, anyway.

One liter is just over 32 oz. I would not call that very close.

The Kaiser Pass is ~9150 ft., and the ride starts at ~350 ft. I had
spent the two prior days at altitude, riding the pass both days
without any discomfort, so I don't think altitude was the problem. I
reached Kaiser Pass at 6.5 hours and felt fine, but 30 minutes later
I was in trouble.

You're probably right then. It's not an altitude adjustment even with
the heftly delta V if you had acclimated to it already.

You're right. The figure "16 oz per qt" got into my head, somehow, and
that's RONG.

A gallon of water is 8.33 pounds or 133.28 ounces.

Correction. A gallon of water is listed as 128 ounces, so it
would seem that one ounce of water is heavier that one
ounce of dry material.

So that would mean that 60 ounces of water is 0.46875 gallons.

"ounce" != "fluid ounce".

"fluid ounce" is a measure of volume. One fluid ounce of a given
fluid will not weigh as much (measured in grams, ounces, pounds,
whatever) as one fluid ounce of another.

128 fluid ounces == 1 gallon. One fluid ounce of water probably does
weigh more than an ounce. It's too late tonight for me to calculate.

Just remember this for water: a pint's a pound the world around.

- 16 oz. per pint (1 lb)
- 2 pints per quart (2 lb)
- 4 quarts per gallon (8 lb)

'tisn't. Imperial Pints are more copious than American ones.

Imperial pint is 568 mL

American pint is 473 mL.

1 L of water @ 4 degC= 1 Kg mass.

Imperial pint is 568 mL

Or, 20 fl. oz.

Or, 16 fl. oz.

And Imperial gallons are 160 fl. oz, while American gallons
are 128 fl. oz.

Ounces are equivalent in both measures, though.

I've heard 'an ounce per minute', and water is just fine.

That's a *lot* of water.

I agree. That's more than 3/4 gallon per hour. On a long ride, I might
drink 1/5 that amount (between 1 and 2 pints per hour, depending on weather).

Playing tennis against a backboard at noon in the middle of summer I
lost 2 pounds (or 32 ounces or 1 quart) of water per hour. I was
working harder then than I've ever worked on a bicycle.

Just a data point.
