Formula reference
mg per mL = ppm / 1000mL needed = desired mg / (ppm / 1000)dose from volume = mL × (ppm / 1000)daily intake = dose per rinse × rinses per daydaily limit = weight × limit mg/kgstock for dilution = (target ppm / stock ppm) × final volume

FAQs
How do I convert ppm to mg of fluoride in a given volume?
Use mg = volume(mL) × ppm/1000. For example, 10 mL at 225 ppm delivers 2.25 mg F‑.
What volume is typically used for a single rinse?
Many products suggest around 10–20 mL per rinse. Check the label of your specific product.
What daily intake limit should I use?
Limits vary by guidance. The default here is 0.05 mg/kg/day, which you can adjust to your context.
Can I plan a dilution to a lower ppm?
Yes. Enter a target ppm and final batch volume. The calculator shows how much stock and water are needed.
Does this account for fluoride from other sources?
No. You should consider toothpaste use, water, supplements, and other sources when assessing total exposure.
Why is my dose per rinse zero?
Set either a desired dose or a planned volume. Without one, the calculator cannot estimate the dose per rinse.
Is this suitable for children?
You can adjust weight and daily limits to model pediatric scenarios. Always follow pediatric guidance and product labeling.
