#' Get the Boundary Radius for a Given Diameter at Breast Height

#' The boundary radius is the maximum distance a tree with a given diameter at

#' @param dbh Diameter at breast height in millimeter.
#' @param unit The unit for the return value.
#' @inheritParams get_correction_factors

#' @details \code{counting_factor} and \code{area} really don't have to be
#' square meters as long as they are in the same unit.
#' @return Minimum diameter at breast height in \code{units}.
