Purpose
These tools provide mathematical conversions using quantities you supply. They do not diagnose, prescribe, recommend a dose or establish the suitability of any compound, solvent or device. They do not replace verified source instructions or qualified professional guidance.
Check source values and devices
Confirm the actual mass, concentration, volume and unit conventions before using a result. The U-100 drawing is illustrative and does not verify a physical device or its graduations. A correct mathematical result can still be inappropriate for the situation in which someone applies it.
Availability and corrections
The application may contain errors or be unavailable. Verify arithmetic independently where precision matters and report suspected defects with the inputs and units needed to reproduce them.
