    Add a tablespoon of ammonium chloride and two teaspoons of sodium sulfite to that, and you should be pretty close to OF-1!

    This must be what gives UK beer a bad name. Pubs that serve it so hot that at room temperture it cools down.

    Never mind the Imperial/Metric debate and beer ...:rolleyes:

    It is probably not a good practice to mix only portions of a pre-mixed powder developer. There is no guarantee that you will get even proportions of the ingredients unless you mix the whole package.

Speaking colloquially, we don't usually specify "fluid" ounces when talking about volumes, because it is assumed that liquids are measured in fluid ounces, and solids and powders are measured by weight, at least when we talk about "ounces" of a solid or powder as opposed to cups or teaspoons.

    The "ounces" on the package should be weight, not volume. If you measured the volume of the powder in (fluid) ounces, it wouldn't likely correspond to the weight of the powder in ounces.

    Just to make life more confusing, precious metals are usually weighed in Troy ounces, and there are 12 of those to a pound.
    Dear David,

    Yes, but there are 20 ounces to a pint and 40 to a quart, not 16 and 32. On the other hand, your fl. oz. are bigger than mine...Another good argument for the metric system, which at least is consistent world-wide.

    And as you say, many old formulae are given in apothecary weight, not avoirdupois. Though I can't remember (and am too lazy to check) whether an apothecary pound is the same as an avoirdupois pound. I'm pretty sure it isn't, and that the ounces are different too -- just like imperial and US measure.

    Cheers,

    Roger

    Yes, this is true. I have no objection to the metric system, but for the purpose of understanding the label on Kodak products, which the original poster asked about, there are 16 US oz to a pound, and they are not the same as fluid ounces, US or British.

    As for reconciling Troy/apothecary weights to avoirdupois, according to Random House Webster's Unabridged Dictionary in Troy weight--

    24 grains = 1 pennyweight (1.555 grams); 20 pennyweights = 1 ounce (31.103 grams); 12 ounces = 1 pound (0.373 kilogram). The grain, ounce, and pound are the same as in apothecaries' weight, the grain alone being the same as in avoirdupois weight.

    Dear David,

    Sorry: didn't mean to muddy the waters still further. I've just come back from a very liquid lunch at the Societé des Ainés Ruraux or Society of Rural Elders.

    I think that weight is the same in both cases; it's just the 'a pint's a pound the world around' (as my wife was taught at school) that confuses matters.

    Thanks very much for the details on the two pounds: 454 g vs. 373 g. So a troy ounce is 31,1g and an avoirdupois ounce is 28,4g, around 10% different. AAARGH! Bring on metrication...

    Cheers,

    Roger

    Totally off topic, but...

    One of my "favorite ounces" is the Ethiopian "Birr". It's defined as the weigth of one Maria-Theresien-Taler, of 1780 date - or 28.0668 g. "Birr" is also the monetary unit of Ethiopia. A "birra" however, is a small bottle of beer (at least in Eritrea).

    Estmado Ole! (I can't seem to get ALT 173, the upside-down !],

    Surely all current Maria Theresa dollars are dated 1780, to avoid confusion...

    But you're right: this is surely the natural unit of measurement.

    Cheers,

    Roger

    Dear jordanstarr,

    I was too lazy to read all the posts so I apologize if this has been stated by others. A fluid ounce is the volume of water that weighs one ounce. It can be very confusing to the uninitiated. I see Roger has already brought up the differences in "Imperial" measures!

    happy birthday roger-i finally feel less intimidated now that i know that i have 5 yrs on you

    when i was a biker in the 60's an "oh zee" was an ounce of la yerba buena but there was allways somebody who would start a serious throw down by claiming that " this oh zee's short-it's only 29grms"-buyers would allways demand a 32 grm oz while those that sold, standardized on the 29 grm oz-how did i live thru all that i wonder?!?!?

    by the way, since you are in acatan, do you speak the local? i only recently found out that my family name is the same as a city very near bilbao-i am andalus moor and the idea that i might also be vasco seems mighty strange at this late date-the political implications are personaly confusing so i think i'll just move to andora and start up my own version of the reconquista refrita

    wanna come along?-i know you still got a black shadow or equivilent stashed some where

    vaya con dios hermanito
