LabReadyTools, the spreadsheet escape hatch for lab math
A free collection of 24 unit-aware chemistry and biology calculators that show their formulas, substituted values, and intermediate steps.
Field notes
The homepage organizes 24 calculators across five laboratory areas, including solution preparation, molecular and cell biology, reaction chemistry, and analytical chemistry. Inputs and outputs are framed around explicit units and visible arithmetic rather than opaque answers: examples include C1 × V1 = C2 × V2 for dilution and y = m·x + b for calibration curves. The Paper to Protocol beta adds a document-based workflow that reviews reported quantities before scaling them to an experiment.
