how much does a suit of plate armor weigh
Plate armour A complete suit of plate armour made from well-tempered steel would weigh around 15–25 kg.[2] The wearer remained highly agile and could jump, run and otherwise move freely as the weight of the armour was spread evenly throughout the body. The armour was articulated and covered a man's entire body completely from neck to toe. In the 15th and 16th centuries plate armored soldiers were the nucleus of every army. Large bodies of men-at-arms numbering thousands or even more than ten thousand men (approximately 60% to 70% of French armies were men at arms and the percentage was also big in other countries) were fighting on foot wearing full plate next to archers and crossbowmen[citation needed]. This was commonly seen in the Western European armies especially of France and England during the Hundred Years War, the Wars of the Roses or the Italian Wars.[citation needed]
Body mass index The body mass index (BMI) or Quetelet index is a value derived from the mass (weight) and height of an individual. The BMI is defined as the body mass divided by the square of the body height, and is universally expressed in units of kg/m2, resulting from mass in kilograms and height in metres.
