Frequently Asked Questions

How much does a human eyeball weigh?

A human eyeball weighs approximately 7.5 grams (0.25 ounces). Most of this weight is the vitreous humor, the clear gel that fills the eye.

How heavy is an African elephant?

Adult African elephants typically weigh between 4,000-7,000 kg, with males averaging around 6,000 kg (13,200 lbs). Asian elephants are somewhat smaller at 4,000-5,000 kg.

What is the heaviest animal?

The blue whale is the heaviest animal ever known, with adults weighing 140,000-190,000 kg (150-210 tons). Their hearts alone weigh about 400 kg.

Can I use this for density calculations?

This calculator only converts mass/weight. For density, you'd also need volume. Fun fact: eyes are slightly denser than water at about 1.05 g/cm³.
