    Ounce for ounce you would use 40% of active dry yeast for the fresh called for in a recipe. So, for example, if your recipe calls for 1 oz of fresh yeast you would use 0.4 oz of active dry.

    One envelope of active dry yeast is 0.25 oz and about 2 1/2 tsp. That makes one tsp about 0.1 oz, near as makes no difference.

    This is from Nick Malgieri at I.C.E.

    There are two principal forms of yeast: Active dry yeast and compressed (also called fresh or cake) yeast.

    Active dry yeast is available in the following varieties: standard, really just cake yeast that has been dehydrated; rapid rise, which rises dough fully in about half the time of standard yeast; and instant blending, which may be mixed directly into flour without first being mixed with liquid, as standard yeast is. Active dry yeast is packaged in retail packages of three ¼ ounce envelopes and in bulk. Store dry yeast in a cool, dark, dry place.

    Compressed yeast is packaged in 2/3-ounce cakes, 2-ounce cakes,1 pound blocks and in bulk --usually 36-pound blocks. Store compressed yeast, tightly wrapped, in the refrigerator. If the surface of compressed yeast becomes moldy, scrape mold off surface, before using.

    To dissolve active dry yeast, whisk it into a warm liquid and allow it to stand several minutes to dissolve; whisk again to disperse the dissolved yeast evenly in liquid. Though yeast dissolves more easily in water, many formulas call for adding yeast to milk. If you are dissolving yeast in milk, be careful that it does not lump when it Is whisked in.

    To dissolve compressed yeast, crumble and whisk it into a warm liquid; compressed
    yeast dissolves immediately in liquid.

    The following conversions make it possible to substitute one form of yeast for another.
    I envelope dry yeast = 2 1/2 teaspoons by volume
    I envelope dry yeast = 1/4 ounce by weight
    I envelope dry yeast = 2/3 ounce compressed yeast in rising power

    Therefore, 2 1/2 teaspoons or 1/4 ounce dry yeast is equal to 2/3 ounce compressed

    1 1/2 envelopes dry yeast = about I plus 1 teaspoon by volume
    1 1/2 envelopes dry yeast = 3/8 ounce by weight
    1 1/2 envelopes dry yeast = I ounce compressed yeast in rising power

    Therefore, I tablespoon plus I teaspoon or 3/8 ounce dry yeast is equal to I ounce compressed

    1. Multiply envelopes of dry yeast by 2/3 to determine ounces of compressed yeast.
    2. Multiply ounces of dry yeast by 8/3 to determine ounces of compressed yeast.
    3. Multiply ounces of compressed yeast by 3/8 to determine ounces of dry yeast.
    4. Multiply ounces of compressed yeast by 3/2 to determine number of envelopes of dry
