Formula Used in “Radiocarbon Dating Calculator (Carbon 14 Dating)”
The fundamental principle of radiocarbon dating is based on the decay of carbon-14 (C14). The standard formula applied in a radiocarbon dating calculator is as follows:
Age (years) = -frac{1}{lambda} cdot lnleft(frac{N}{N_0}right)
Where:
- Age: The age of the sample in years
- lambda: The decay constant for carbon-14, approximately 1.21 x 10-4 years-1
- N: The remaining quantity of carbon-14 in the sample
- N0: The initial quantity of carbon-14 at the time of the organism’s death
Step-by-Step Breakdown of the Formula
In order to determine the age of a sample using the radiocarbon dating formula, follow these steps:
- Identify N0: Determine the initial amount of carbon-14 when the organism died.
- Measure N: Quantify the current amount of carbon-14 remaining in the sample using mass spectrometry or liquid scintillation counting.
- Calculate lambda: Use the known decay constant for carbon-14, which is approximately 1.21 x 10-4 years-1.
- Insert values: Plug the values of N, N0, and lambda into the formula.
- Perform calculations: Use natural logarithm (ln) and complete the mathematical operations to find the age of the sample.
Example Calculation
To illustrate the radiocarbon dating process, we will use a fictitious example of a wooden artifact that contains 10 mg of C14. The initial carbon-14 amount (N0) when the tree died is estimated to be 15 mg. Using the decay constant (lambda), we can calculate the age of the wooden artifact.
| Input Variable | Value |
|---|---|
| N0 (Initial C14 amount) | 15 mg |
| N (Remaining C14 amount) | 10 mg |
| (lambda) (Decay Constant) | 1.21 x 10-4 years-1 |
Now let’s substitute the values into the formula:
Age (years) = -frac{1}{1.21 times 10^{-4}} cdot lnleft(frac{10}{15}right)
Calculating the natural logarithm:
(ln(10/15) approx -0.4055)
Now substituting this value to get the age:
Age ≈ -frac{1}{1.21 times 10^{-4}} cdot (-0.4055)
Age ≈ 3355 years
This calculation indicates that the wooden artifact is approximately 3355 years old.

Radiocarbon dating, also known as Carbon-14 dating, is a scientific method used to determine the age of organic materials by measuring the amount of Carbon-14 they contain. It is effective for dating materials up to about 50,000 years old.
How does the radiocarbon dating calculator work?
The radiocarbon dating calculator uses the half-life of Carbon-14 (approximately 5,730 years) to estimate the age of the sample based on measured levels of Carbon-14 compared to stable carbon isotopes like Carbon-12.
What types of materials can be dated using Carbon-14?
Carbon-14 dating can be applied to various organic materials, including wood, charcoal, bone, shells, and textiles. However, it is not suitable for inorganic materials like metals or stones.
What is the limit of carbon dating accuracy?
The accuracy of radiocarbon dating is generally reliable up to about 50,000 years. Beyond this age, the amount of Carbon-14 is diminished to a level that makes it difficult to measure accurately.
