Wekagram (Wg) is the unit of mass equal to 1027 kilograms, or 0.5267 Jupiter masses or 167.4 Earth masses. It would be most useful for measuring masses of giant gas planets in metric units besides Jupiter masses and kilograms. But for rocky planets, xentagram (Xg), which is 0.001 Wg, can be used besides Earth masses and kilograms. For stars, vundagram (Vg), equalling 1000 Wg, can be assigned besides solar masses and kilograms. For moons, asteroids and other small celestial bodies, yottagram (Yg), which is one-millionth of a wekagram, can be used in addition to Lunar masses and kilograms.
