What is the crown-rump measurement of a fetus, 9 weeks from conception?

Answer by  Cali2307 (1337)

All of the measurements in the first trimester are crown to rump measurements. At 11 weeks of pregnancy, your baby should be about one and a half inches long.

Your baby is probably 2. 5 cm or about an inch. In other words, very tiny still. Wish you the best!

The baby measures 2 1/2 to 3 inches and weights 1 1/2 ounces by the end of the 3rd months.

At this point, the developing fetus is about 50 millimeters from crown to rump and weighs about eight grams, which is about a quarter of an ounce. It will grow another 10-15 millimeters each week (about a centimeter to a centimeter-and-a-half) over the next several weeks.
