Calculate average sediment accumulation rate from stratigraphic depth and dated time span. Free online tool with instant results — no signup required.
Calculate artifact density per square meter from excavation counts and area. Free artifact density calculator for artifact, density, and more.
This tool applies a standard formula from the relevant domain. The computation is deterministic — given the same inputs, the result is always identical. The formula accounts for the primary variables that determine the output.
Calibrated age = Radiocarbon age + Reservoir offsetThe calculation requires: Radiocarbon Age, Reservoir Offset (ΔR). Each parameter contributes to the final result according to the formula above. Accuracy depends on the precision of your input measurements.

This calculator uses the formula shown. Real-world results may vary due to factors not captured by the model. Use the result as an estimate and verify with domain-specific standards.
Apply marine or regional reservoir correction to radiocarbon dates for cultural layers. Free cultural layer dating offset tool for cultural, layer, and more. It applies the calculation formula (Calibrated age = Radiocarbon age + Reservoir offset). For example: 3200 bp + 400 yr marine offset — A typical use case demonstrating the calculator with representative values.
