Baby weight has a significant meaning in determining diagnosis, delivery plan, and referral. Uterus fundus height measurement can be used as an indicator in the assessment of estimated gestational age and estimated fetal weight. Ideally, the measurement of the estimated fetal weight is measured using sophisticated equipment. However, in Indonesia, many deliveries are still carried out in basic services. They are limited by authority; it is necessary to develop reliable but straightforward measurement techniques. The purpose of this research is to determine the differences in the results of the calculation of the simple formula, the dare formula, and the Johnson Toshack formula in calculating the estimated fetal weight at the Batujajar Community Health Center. This research is an analytical survey research with a cross-sectional approach. There were 160 mothers involved as samples who gave birth in June-October 2020 at the Batujajar Community Health Center who met the inclusion and exclusion criteria. The data obtained were analyzed using the T-test and multiple linear regression. The results showed that there was no difference between the calculation of the simple formula (p-value = 0.188) and the dare formula (p-value = 0.734) in calculating the estimated fetal weight. There is a difference between the Johnson-Toshack formula's calculation with the newborn's actual weight (p-value = 0.001). The regression test results showed that the dare formula is more accurate in calculating the fetal body weight measurement with an r = 0.999. In conclusion, the dare formula is more accurate in calculating the estimated fetal weight.
