Thirty-nine adult Indian elephants (Elephas maximus indicus) of both sexes and various ages and weights, belonging to the Forest Department of the Government of Kerala (India), Temple Devaswoms, Gemini Circus and other private agencies, were used to derive formulae to predict body weight and height from body measurements. Several models were fitted separately for males and females and also for adults irrespective of sex. The best prediction of body weight (W) in kg was obtained for adults irrespective of sex by using two parameters, the body length (L) in cm from the base of the forehead to the base of the tail, and the chest girth (G) in the formula W = -1010 + 0.036 (L x G). No single parameter gave as accurate a prediction of the body weight, and the inclusion of height as a third parameter did not improve the prediction. No significant improvement in the accuracy of prediction resulted from the use of different formulae for males and females. An equation to predict the height at the shoulders (H) in cm from the right forefoot circumference (C) in cm in adult elephants irrespective of sex was also derived. This was H = -1.60 + 1.99 C.
39头成年印度象（印度象亚种），雌雄皆有，年龄和体重各异，分别隶属于印度喀拉拉邦政府森林部门、寺庙德瓦斯沃姆、双子马戏团及其他私人机构，被用于推导通过身体测量来预测体重和身高的公式。分别为雄性和雌性，以及不分性别的成年象拟合了多个模型。对于不分性别的成年象，通过使用两个参数——从额头基部到尾基部的体长（L，单位为厘米）和胸围（G），利用公式W = -1010 + 0.036（L×G），能得到对体重（W，单位为千克）的最佳预测。没有单个参数能给出如此准确的体重预测，并且将身高作为第三个参数并未改善预测效果。使用针对雄性和雌性的不同公式，预测准确性没有显著提高。还推导了一个公式，用于根据成年象不分性别的右前足周长（C，单位为厘米）来预测肩部高度（H，单位为厘米）。公式为H = -1.60 + 1.99C。
