Abstract The propagation law of errors in total least squares（TLS）was proposed. The covariance matrix of the first column vector can be determined when the first column vector equals the product of one variable matrix and the second column vector, and the variance and covariance of all the elements in the variable matrix are known. The propagation law of errors between two relevant variable matrixs can be reducted. Some examples indicate that the law is effective.
