I use mostly metric measuring, that´s how I calculate. The basic conversion equivalents to help visitors who are familiar with the US standard are given below to save a few valuable minutes of your time.
Weight:
14 g = 1/2 oz
28 g = 1 oz
56 g = 2 oz
113 g = 4 oz = 1/4 lb
149 g = 51/4 oz = 1/3 lb
226 g = 8 oz = 1/2 lb
342 g = 12 oz = 3/4 lb
453 g = 16 oz = 1 lb
680 g = 24 oz = 1 1/2 lb
907 g = 32 oz = 2 lb
Temperature:
120 Celsius = 250 Fahrenheit
140 Celsius = 275 F
150 Celsius = 300 F
160 Celsius = 325 F
175 Celsius = 350 F
190 Celsius = 375 F
200 Celsius = 400 F
220 Celsius = 425 F
230 Celsius = 450 F
