The Weight Tape Formula
Why Accurate Weight Matters

A Fórmula

Peso (kg) = (Perímetro torácico² × Comprimento) ÷ 11.877. O perímetro se mede atrás dos cotovelos. O comprimento da ponta do ombro à ponta da nádega. Cavalo médio: 400-600 kg. Pônei: 200-400 kg. Cavalo de tração: 700-1.000 kg. Precisão ±5%. No Brasil, o Mangalarga Marchador pesa tipicamente 400-550 kg.

Importância

Dosagem de vermífugo se calcula por peso. Erro de 20% = sub ou sobredosagem. Carga do cavaleiro: máximo 20% do peso. Cavalo de 500 kg: cavaleiro + sela máx 100 kg.

⚡ CalcWolf Insight

Horse weight calculator has a small but dedicated niche audience (10K/mo searches). Horse owners are high-value consumers — average annual spending per horse is $3,500-10,000. Equine supply advertisers (SmartPak, Dover Saddlery) are willing to pay $5-12 CPC for this audience.
