Best way for mobile users to input big numbers

I am struggling to figure out best way for mobile users (both Android and iOS) users to input big numbers in form. There are need to insert handful of percentages ranging from 0% - 100%, which is easy one to implement. Problematic is inserting handful of weights, ranging from 1g to up to maybe 10 000g. And ideally going in increments of 0.1g or 0.5g. Most values are around 10 - 2500g. Anyone have good examples how to make it easy and effective? Maybe even know ready React component for this?
