Percent to ml-per-Litre Spray Converter
Convert a spray concentration between percent (%) and millilitres or grams per litre of water.
A 1% w/v solution is 10 ml (or 10 g) per litre of water. To convert any percentage, multiply by 10 for ml (or g) per litre. This is the commonest spray-mixing conversion when a label gives a percentage but you mix by the tank.
Always follow the product label — the label is the law. Verify doses, PHI and compatibility with the manufacturer and local regulations before spraying.

About Percent to ml-per-Litre Spray Converter
Pesticide and foliar-spray labels sometimes give a percentage strength while you mix by the litre or tank — and getting the conversion wrong by a factor of ten is a classic, damaging mistake. The rule is simple: a 1% solution is 10 ml (or grams) per litre of water. This tool converts any percentage into millilitres/grams per litre and per tank, so you measure exactly the right amount for the concentration the label specifies.
