That would be a hard one: I'm assuming you're looking at a chemical application, and ratios like that are meant to inform the applicator once he is familiar with his equipment. Applicators always spray as either a mixture or emulsion with water, knowing how far a gallon of water goes in that equipment: enough water to spray 100 acres of crops needs 70-150 pints of concentrate.

To use those figures in your garden you need to know how far a gallon of water will take you. Suppose your intended patch is 66 ft on a side (4356 sq ft, or 1/10 acre) and you intend to cover it with spray. You'd need (range of .7-1.5 divided by 10) in whatever amount of spray youi will apply.

There are 16oz in a pint
2 TBSP oz, or each TBSP is 1/32 or .03125 pint
3 tsp TBSP or 1 tsp is 1/6 oz.

taking your product at 1 pint/acre (acre is 43560 ft/2) that requires you to use 1/10 pint in your 1/10 acre; thats 1.6 oz, or approximately 3 TBSP + 2 tsp per application, or 11 tsp.

Suppose you want to use 3 gallons of spray mix to treat your 1/10 acre: 11 tsp/ 3 gallons.

Since there is 43560 sq ft/acre, 1 pint/43560 gives you the amount per sq ft. The smallest measurement in most measuring spoons is 1/8 tsp, or 1/768 pint. This would treat a 7-1/2 foot square. But measuring spoons are meant to measure dry quantities like spices which are different than liquid measurements AND THEY ARE NOTORIOUSLY INNACURATE.

This really a long way to say that using concentrated and possibly dangerous agricultural chemicals with inaccurate home and garden equipment is difficult at best, and usually not advised.
