Pregnant Weight Gain Calculator

Pregnancy is a transformative journey marked by various physical changes, including weight gain. Monitoring weight gain during pregnancy is crucial for the well-being of both the mother and the baby. To simplify this process, we introduce the Pregnant Weight Gain Calculator, a handy tool for expectant mothers.

Formula: The calculator utilizes a straightforward formula: weight gain is estimated by adding 1.0 pound for every week of pregnancy divided by 9.0. This formula provides a reasonable approximation of the weight gain expected during pregnancy.

Example: Suppose a woman with a pre-pregnancy weight of 140 pounds is 20 weeks pregnant. The estimated weight gain would be calculated as follows: Weight Gain=1.0+(209.0)Weight Gain=1.0+(9.020​) Weight Gain=1.0+2.22Weight Gain=1.0+2.22 Weight Gain=3.22Weight Gain=3.22 Estimated Weight Gain=140 pounds×3.22 (calculated weight gain)=450.8 poundsEstimated Weight Gain=140pounds×3.22(calculated weight gain)=450.8pounds
