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.
Tc = temperature in degrees Celsius, Tf = temperature in degrees Fahrenheit. To convert a Fahrenheit temperature into Celsius: Tc = (5/9)*(Tf-32) For example, to convert a Fahrenheit temperature of 98.6Â°F into degrees Celsius, first subtract 32 from the Fahrenheit temperature to get 66.6.
