Q:

How do you calculate urine output per hour based on body weight?

A:

Calculate urine output per hour by dividing each kilogram of body weight by 0.5 milliliters, according to EasyCalculation.com. This is the minimum expected hourly urine output for an average adult. For children, the expected output per hour is about 1 milliliter per kilogram of body weight.

Urine consists mostly of water, along with salts, hormones and proteins, notes Wikipedia. It varies in appearance, mostly depending on the hydration level in an individual's body. Urine with no color can indicate that an individual is too hydrated, and dark yellow urine can indicate dehydration. A light orange color may indicate excessive loss of B vitamins from the body. Urine color is also affected by the consumption of certain foods; for example, eating asparagus can cause green urine.
