Example: 2 lb cornstarch (quantity in recipe) x 2.61 (working factor) = 5.22 lb cornstarch (quantity to use). Volume Adjustment First obtain a working factor by dividing the number of servings needed by 100 as shown in step 2. 333 ÷ 100= 3.33. Then multiply the quantity of each ingredient by the working factor. You will round off to the nearest 1/4 teaspoon. For example, the recipe calls for 6 gallons of water per 100 portions. Portions to prepare are 333. 333 ÷ 100= 3.33 working factor (w/f). Step 1. w/f x gallons (recipe)= gallons to use 3.33 w/f x6 gl 19.98  gl Step 2. Decimal (of gal) x 4 = quart .98 gl x4 qt 3.92 qt Step 3. Decimal (of quart) x 2 = pint .92 qt x2 pt 1.84 pt Step 4. Decimal (of pint) x 2 = cup .84 pt x2 c 1.68 c Step  5.  Decimal  (of  cup)  x  16=  tablespoon  .68  c x16 tbsp 10.88  tbsp Step 6. Decimal (of tbsp) x 3 = teaspoon .88  tbsp x3 tsp 2.64  tsp Step 7. Round off tsp decimal portion .64 tsp is equal to 3/4 tsp Thus, the amount of water needed for 333 portions is 19 gl, 3 qt, 1 pt, 1 c, 10 tbsp, and 2 3/4 tsp. CONVERTING   AND   ROUNDING   CALCU- LATED QUANTITIES.— When a recipe is increased or  decreased  or  ingredient  quantities  are  altered  it  is usually  necessary  to  convert  the  amount  calculated  to another unit of measure because, in most instances, a part of a pound or a partial measure results. To obtain a usable figure, (a) round off the calculated figure given in decimal pounds or measures to a whole figure or (b)  convert  partial  pounds  into  ounces  and  the  partial measures into smaller units; for example, partial quarts into  cups. CONVERTING FRACTIONAL WEIGHTS.— When  increasing  or  decreasing  recipes,  the  division  or multiplication of pounds and ounces is expressed as decimals  to  simplify  cumbersome  fractions.  For example, if the quantity of an ingredient is multiplied by a working factor, the calculation is as follows: 1.25 lb x 3.48 (working factor)= 4.35 lb. The  quantity,  4.35  pounds,  could  be  expressed  by converting the fractional part of the pound into ounces. Another  means  of  converting  fractional  parts  of  a pound is to make the calculation instead of consulting the conversion table. The part of the pound is converted to ounces by multiplying the figure by 16 ounces. For example: 0.35 x 16 oz = 5.60 oz. ROUNDING OFF WEIGHTS.— After the part of the  pound  has  been  converted  to  ounces  (0.60),  as indicated   in   the   Recipe   Conversion   Card   A-1(1), decimals may be rounded off to provide whole units of weights  or  measure. Round off decimal weights as follows: Decimal Round  to 0.01 to 0.12. . . . . . . . . . . . . . . . . . . . .  . .0.00 or oz 0.13 to 0.37. . . . . . . . . . . . . . . . . . . . . . 0.25 or 1/4 oz 0.38 to 0.62. . . . . . . . . . . . . . . . . . . . . . . 0.50 or 1/2 oz 0.63 to 0.87 . . . . . . . . . . . . . . . . . . . . . . . 0.75 or 3/4 oz 0.88 to 0.99. . . . . . . . . . . . . . . . . . . . . . .1.00 or 1 oz Using the previous example, the 4.35 pounds (or 4 pounds 5.60 ounces) would be rounded to 4 pounds 5 1/2 ounces. ROUNDING  OFF  VOLUME  MEASURES.— When  converting  volume  measures,  rounding  off  is  also necessary.  Round  off  volume  measures  as  follows: Calculated  volume Measure Round to 5 gal or more. . . . . . . . . . . . . . . .Closest full qt 5 1/4 qt to 4 3/4 gal . . . . . . . . . . . . . Closest full cup 5-8
