WebThe half life of carbon-14 is about 5,700 years, so if we measure the proportion of C-14 in a sample and discover it's half a part per trillion, i.e. half the original level, we know the sample is around one half life or 5,700 years old. So by measuring the C-14 level we work out how many half lives old the sample is and therefore how old it is.
