Water, about 125ºF (50ºC) - 64 fl. oz. - 2.0L - 80 fl. oz.
Elon - 60 grains - 4.0g - 72 grains
Sodium Sulfite, desiccated - 10 oz. avdp. - 300.0g - 12 oz. avdp.
Hydroquinone - 520 grains - 36.0g - 624 grains
Sodium Carbonate, desiccated - 3 oz. avdp. 147.5 grains - 100.0g - 4 oz. avdp.
Potassium Bromide - 292 grains - 20.0g - 350 grains
Cold Water to Make - 1 U.S. gallon - 4.0L - 1 Imp. gallon

Metric measurements are exact. U.S. Customary measurements supplied. Imperial measurements accurate to within 1 grain, 2 grains on measurements 875 grains or larger in weight.

It would be more sensible to give chemicals their correct names,
Elon is actually Metol. Also to list the formula as published by Kodak rather than the US Navy, ie to make 32 US ounces and 1 litre.

This goes for all the other formulae you've posted, they have all been published extensively by Kodak themselves.

The correct versions of these Formulae are very easy to find and are published in a wide array of publications. So it's not nitpicking to suggest listing them properly as opposed to the bulk solutions in the Naval handbook

No-one uses Imperial weights etc to make up formulae, scales in the UK and elsewhere are now all metric, and even older scientific scales have been metric for a great many years, certainly more than 50 !!!!!.

I will also ask why is this different then any other developer. Just would like more information.

D-19, D-11 and D-8 are a series of high contrast film developers. Each has a higher contrast than the other in a series, but all I can remember is that D-19 is the lowest of them all. The series starts with D76, which is the normal developer.

To make D-11 out of D-19: to the dry ingredients of a 1 gallon size of D-19, add 38 grams of hydroquinone and 230 grams of dessicated sodium sulfite and water to make 2 gallons.

In our electron microscopy labs we use KODAK D-19 Developer for developing electron microscope films (including Kodak Technical Pan). We also use it for other types of scientific and technical photography. We use it in these applications primarily for its high contrast characteristics.
