Some insight you may find interesting:Flour:
Always sift your flour no matter what type you buy. It is proven that when measured by "volume"
sifted flour will weigh more consistently when sifted as opposed to not sifted before use in a recipe. This is not applicable for measuring only by weight.Weights and Measures Conversion Calculator
Very handy in a pinch. Quantities may even be entered using fractions if required.Measuring Oven Accuracy
There is a wonderful article in the March 2002 issue of Cook's Illustrated. It discusses the calibration of ovens both of commercial quality and residential use and the wide variations between each oven, how they heat in what areas of the oven, how they "maintain" the target temperature, and the differences which leads to the issue of thermometers.
They end up rating thermometers and highly recommend an inexpensive oven thermometer over high priced ones.Measuring Thermometers:Boiling Water Test
The most common way to test a thermometer is to place it in boiling water. An accurate thermometer will read about 212*F in boiling water at sea level under normal atmospheric conditions.
To test your thermometer, bring a pot of water to a vigorous boil. Hold the thermometer stem or probe in the water, making sure not to touch the sides or bottom of the pot, and take your reading.
Remember that there are several factors that affect the boiling point of water:
*As atmospheric pressure decreases, the boiling point decreases. Atmospheric pressure will vary depending on your altitude and local weather conditions.
*Hard water boils at a temperature 1-2*F higher than soft water, due to dissolved mineral salts.
*Using a tall, narrow pot will result in a boiling point about 1*F higher than a short, wide pot.
If you live at high altitude, you'll need to take that into account when testing your thermometer. The table below lists the approximate boiling point for a number of different altitudes. As a general rule, the boiling point decreases approximately 1.8*F for every 1000-foot increase in altitude. Note that the actual boiling point may be higher or lower depending upon atmospheric pressure in your area on any given day.

Another way to determine your boiling point is to use a Boiling Point Calculator
. By entering your current barometric pressure and your elevation, you can get a good estimate of your boiling point.

Using standard size dry measuring cups, gently spoon ingredients into the measuring cup. When the container is full, level off with a knife. Scooping or tapping a measuring cup will pack the ingredients, and there will be more than is required in the cup. This extra amount could affect the balance of the recipe. Level dry ingredients with a knife.
Weigh the measurement with your scale and write it down on your recipe or keep notebook, journal or software file where you log the ingredients you use and how much say 1 Tbls of "cornstarch" weighs. If your recipe comes out correctly, the next time you use your scale and need one tablespoon of cornstarch, you won't have to break out your measuring spoon.
Also, you can just keep adding to the "like" ingredients on your scale by zeroing out between each ingredient and this will save you on the number of items you'd normally have for clean up.
