Introduktion
NPK Ratio Calculator — Actual kg of N, P and K in a fertilizer bag. Enter Bag weight (kg), N %, P %, K % to get an instant, accurate result.
Formel
Actual nutrient content (kg) = bag weight × nutrient percentage / 100, applied separately to N, P, and K using the fertilizer's guaranteed analysis.
Trin for trin
- Enter the Bag weight (kg).
- Enter the N %.
- Enter the P %.
- Enter the K %.

Eksempel fra virkeligheden
Example: With Bag weight (kg) = 50, N % = 10, P % = 20, K % = 10, the NPK Ratio Calculator gives N Kg: 5, P Kg: 10, K Kg: 5.
Ofte Stillede Spørgsmål
What do the three N-P-K numbers on a bag mean?
They are the guaranteed percentage, by weight, of nitrogen (N), phosphorus as P2O5 (P), and potassium as K2O (K) in that bag.
Why does this matter for blending?
Knowing the actual kilograms of each nutrient per bag lets you combine fertilizer products to hit a specific N-P-K target instead of guessing from bag counts alone.
What inputs does the NPK Ratio Calculator need?
You'll need to provide: Bag weight (kg), N %, P %, K %. All fields use sensible defaults, so you can see a working example immediately and then adjust the values to match your own numbers.
How accurate is the NPK Ratio Calculator?
The NPK Ratio Calculator applies the formula exactly as calculated — Actual nutrient content (kg) = bag weight × nutrient percentage / 100, applied separately to N, P, and K using the fertilizer's guaranteed analysis. — so results are precise for the inputs you provide. Accuracy depends on entering correct, realistic input values.
Is the NPK Ratio Calculator free to use?
Yes, the NPK Ratio Calculator is completely free, requires no signup, and runs instantly in your browser.
Om NPK-forholdsberegner
The NPK Ratio Calculator uses a real, verifiable formula — Actual nutrient content (kg) = bag weight × nutrient percentage / 100, applied separately to N, P, and K using the fertilizer's guaranteed analysis. — so results are accurate every time, not an approximation.
