Since blood production requires iron, you should eat iron-rich foods for two weeks before your appointment. This will help you have strong blood for donation and help you better recuperate after your donation. Iron-rich foods include spinach, whole grains, fish, poultry, beans, organ meat, eggs, and beef.
To calculate the change in temperature, subtract the initial temperature from the final temperature. Example: 84.2 degree Fahrenheit - 41 degrees Fahrenheit = 43.2 degrees Fahrenheit. The temperature from morning to afternoon changed by 43.2 degrees Fahrenheit.
You take the Fahrenheit temperature and subtract 32, then you divide that number by 9/5 and whatever that equals is the Celsius temperature for example: 65 degrees Fahrenheit â¦ 65 -32 = 33 33 / (9/5) or because of the rules of dividing fractions 33 X (5/9) it is 18.33 degrees Celsius.
