Carbon Dating
A precise tool.
What is the Carbon Dating & How does it work?
Carbon dating is a method used to determine the age of an object containing organic material by measuring the amount of carbon-14 ((^{14}text{C})) it contains. Carbon-14 is a radioactive isotope of carbon that decays at a known rate, allowing scientists to estimate the time elapsed since the death of the organism.
The decay constant (lambda) for carbon-14 is approximately 0.000121 per year. This method is effective for dating objects up to about 50,000 years old.
t = frac{-ln(frac{N_t}{N_0})}{lambda}
t = time elapsed, N_t = amount of carbon-14 at time t, N_0 = initial amount of carbon-14, lambda = decay constant
The decay constant (lambda) for carbon-14 is approximately 0.000121 per year. This method is effective for dating objects up to about 50,000 years old.

Frequently Asked Questions
How do I use the Carbon Dating Calculator?
Enter the initial amount of carbon-14 (N0) and the current amount of carbon-14 (Nt). The calculator will then compute the time elapsed using the decay constant.
What is the decay constant for carbon-14?
The decay constant for carbon-14 is approximately 0.000121 per year.
Can I use this calculator for any type of material?
This calculator is specifically designed for organic materials that contain carbon-14, such as fossils or ancient artifacts.
What does the result from the calculator represent?
The result represents the estimated age of the organic material in years since it stopped taking in carbon-14.
How accurate is carbon dating?
Carbon dating can be quite accurate for materials up to about 50,000 years old. Beyond this, the amount of carbon-14 remaining becomes too small to measure accurately.
Can I use this calculator if I only know the percentage of carbon-14 left?
Yes, you can convert the percentage of carbon-14 left into a fraction and use it as Nt/N0 in the formula.
What is the half-life of carbon-14?
The half-life of carbon-14 is approximately 5,730 years.
