Title: A Cosmology Calculator for the World Wide Web

Authors: Edward L. Wright (UCLA)

(Submitted on 20 Sep 2006 (v1), last revised 10 Oct 2006 (this version, v2))

Abstract: A cosmology calculator that computes times and distances as a function of redshift for user-defined cosmological parameters is available on the World Wide Web. This note gives the formulae used by the cosmology calculator and discusses some of its implementation. A version of the calculator that allows one to specify the equation of state parameter w and w' and neutrino masses, and a version for converting the light travel times usually given in the popular press into redshifts are also available.

Comments:	8 pages with 1 included figure. Cosmology calculator available at this http URL, light travel time converter at this http URL and the advanced cosmology calculator at this http URL Revised to fix a typo, add a reference, and match the accepted version to be published in the PASP
