μM <–  –> mg/L    

Working with plant tissue culture often requires using plant hormones, or plant growth regulators (PGRs).  Media formulations given in the literature can present hormone amounts in either mg/L (=ppm) or μM and comparing protocols can mean converting back and forth between these units.  The following tool will convert between mg/L and μM for many of the most commonly used hormones.

If you have suggestions for additional hormones to add to the calculator, please send them to: [email protected].

The Hormone Calculator converts between uM and mg/L for many of the most commonly used plant hormones.
