How to use the lineweaver–burk plot calculator
Find Vmax and Km from a double reciprocal line. Enter slope (km/vmax), y-intercept (1/vmax) in the fields above; the vmax, km are computed instantly and plotted on the chart so you can see how the answer changes.
Formula
Variables
- sl — Slope (Km/Vmax)
- ic — Y-intercept (1/Vmax)
Worked example
With slope (km/vmax) = 0.02, y-intercept (1/vmax) = 0.01, the calculator gives vmax ≈ 100; km ≈ 2.
Frequently asked questions
What is the formula for the lineweaver–burk plot calculation?
Vmax = 1 / ic. Km = sl / ic. Here sl is slope (km/vmax), ic is y-intercept (1/vmax).
What inputs do I need for the lineweaver–burk plot calculator?
You need slope (km/vmax), y-intercept (1/vmax). Each field is pre-filled with a typical example so you can see how the result responds as you edit the numbers.
How do I use this calculator?
Type values into the input fields. Results and the chart update instantly. Use Reset to restore the example values, Copy results to paste them elsewhere, or Share to copy a link that preserves your inputs.
Is the result exact?
Calculations use standard formulas and double-precision arithmetic, then display about seven significant figures. Real-world measurements carry uncertainty, so treat results as estimates unless your inputs are exact.
