Unit conversion

Units of measure (lab) conversions

From one unit to another

More than 400 lab and unit conversions such as hormones, blood sugar, length, weight, and many others.

A) Needed values

To convert the laboratory results from one unit to another, you need the following values:

  1. The measured value (in the unit you want to convert from)

B) Steps

  1. In the Input table: put the previous value into the corresponding cell

  2. Choose the units you want; from the available list

  3. Click submit

C) Equations

The output was calculated upon the following conversion factors (with the list of available substances arranged alphabetically):
