What the Omega-3 / Omega-6 Ratio Calculator calculates
Calculate the omega-6 to omega-3 ratio from like-for-like intake estimates.
The page keeps absolute amounts visible and does not present a disputed universal “ideal ratio” as settled fact.
How to use the Omega-3 / Omega-6 Ratio Calculator
- Use the same period for both inputs.
- Use total-to-total or a clearly matching fatty-acid scope.
- Enter amounts in grams or milligrams.
- Interpret the ratio with absolute intake.
Continue with the TDEE Calculator. Keep whole-day energy needs separate.
Formula, variables and calculation order
omega-6 : omega-3 = omega-6 grams / omega-3 grams.
Inputs are validated and normalized before calculation. Full precision is retained until the displayed result is rounded.
Cross-check a different part of the decision with the Macro Calculator. Translate an energy target into macronutrients.
Worked example and boundary check
Worked example
12 g omega-6 and 2 g omega-3 gives 6:1.
Boundary check
Comparing total omega-6 with only EPA+DHA creates a mismatched ratio.
How to interpret the result
Use the ratio as descriptive arithmetic. Do not infer deficiency, inflammation, or treatment need from the ratio alone.
- Food-log fatty-acid estimates can be incomplete.
- Different omega-3 and omega-6 fatty acids have different contexts.
- No universal ideal treatment ratio is applied.

Inputs, outputs and result meaning
Prevents ratio-only interpretation by retaining the absolute total and omega-3 share.
Inputs
- Omega-6 intake
- Use intake from the same period and the same scope. Supported units are grams (g) and milligrams (mg).
- Omega-3 intake
- Use total omega-3 only if the omega-6 number is also total intake. Supported units are grams (g) and milligrams (mg).
Outputs
- Omega-6 : omega-3 ratio
- This is the primary result. It is displayed in :1. The display rule uses up to 2 decimal places.
- Omega-3 share of entered total
- It is displayed in %. The display rule uses up to 1 decimal places.
- Entered omega-3 + omega-6
- It is displayed in g. The display rule uses up to 2 decimal places.
- Omega-3 used
- It is displayed in g. The display rule uses up to 2 decimal places.
Ratio = omega-6 intake / omega-3 intake. Keep the result label, unit, selected mode, and stated limitations together when sharing the answer.
Frequently asked questions
What is the ideal ratio?
The calculator does not assert one universal treatment target.
Can I mix mg and g?
Yes; units normalize before division.
Should I include ALA?
Use the same scope on both sides and document what you included.
Does the ratio diagnose inflammation?
No.
