In your ultrasound the head circumference and abdominal diameter were the same length but the femur lenght was smaller which is more accurate?

I have had many conflicting ultrasounds. I had the exact opposite problem- the femur length was a week further in gestation than the head or abdomen, and the estimated weight put her a week further along than her femur. What my ultrasound technician told me was to trust in the initial date given by the obgyn when I had my very first ultrasound (I was only 5 weeks at my first appt). The earlier the scan, the less the variation in size. I am 5'1, but with those long legs, I guess our little girl is going to be 6'5 like her daddy!

How do you get diameter from circumference?
Circumference is Pi x Diameter so do Circumference divided by Pi to get the diameter :)
If you have your circumference how do you find the diameter?
diameter = circumference/pi
WHats the diameter of a circle with a circumference of?
circumference = diameter * pi. Therefore, diameter = circumference ÷ pi.
What is the diameter of a circle with the circumference of 5?
Circumference = pi*diameter So diameter = circumference/pi = 1.59 units
Is there a relationship between the circumference and the diameter of a circle?
Yes because: circumference/diameter = pi and circumference = pi*diameter
Is measuring the femur bone in an ultrasound an accurate way to give you an estimated time of conception?
The best person to ask is the person doing the ultrasound. Having said that here are a few guidelines. Ultrasounds can give you a fairly accurate time for the length of the pregnancy. Before 10 weeks the measurement taken is crown-rump length, from the top of the head to the bottom of the spine. This is accurate to within 3-4 days. After about 12 weeks several measurements are taken, head circumference, head diameter and abdominal diameter as well as femur length and the results are plotted on a graph to compare with the estimated length of pregnancy. The earlier the measurements are taken the more accurate they are in assessing the length of the pregnancy.

An introduction of pi?
Pi is the ratio of the circumference of a circle to its diameter; it can be calculated as circumference divided by diameter, or circumference/diameter. It is an irrational number which starts 3.14159265358979323846264338327050..., but it is usually approximated to 3.14 or 22/7, though using the [π] button on a calculator makes it easier to enter a fairly accurate value.
What is 3.1425?
That is called pi, the ratio between the diameter and the circumference of a circle. Of course, 3.14159265 is more accurate.
How do you figure out diameter and circumference?
Circumference is pi times diameter. Diameter is circumference divided by pi. Diameter is twice the radius. Radius is half the diameter.
How do you find the diameter from the circumference?
Diameter = Circumference/pi
If you have your circumference how do you find the diameter?
diameter = circumference/pi
What is the diameter of a 12cm circle?
using the formula circumference=diameter X pi: circumference=diameter X pi circumference/pi=diamter X pi/pi circumference/pi=diameter therefore, diameter=circumference/pi diameter=12mm/3.14 diameter=3.821mm
What is the equation to get the diameter from the circumference?
Since the circumference is Pi times the diameter then divide the circumference by Pi (3.14159) to get the diameter
What is the circumference of A 13.5 Diameter circle?
The circumference of a 13.5 diameter circle is: 42.41(diameter x pi = circumference).
The circumference of a circle is 31mi what is it diameter?
Circumference = pi*diameter So diameter = circumference/pi = 9.87 mi
If a circle has a circumference of 8 what is the diameter?
If a circle has a circumference of 8 the diameter is: about 2.546 (circumference divided by pi = diameter).
