## How big is an explosion from TNT?

Table of Contents

An independent study by experts from the Blast and Impact Research Group at the University of Sheffield predicts the best estimate of the yield of Beirut explosion to be 0.5 kilotons of TNT and the reasonable bound estimate as 1.12 kilotons of TNT.

### How many kilotons was the Halifax explosion?

2.9 kilotons

1,782 people were killed, largely in Halifax and Dartmouth, by the blast, debris, fires, or collapsed buildings, and an estimated 9,000 others were injured. The blast was the largest human-made explosion at the time, releasing the equivalent energy of roughly 2.9 kilotons of TNT (12 TJ).

#### How many kilotons is TNT?

1,000 tons

Thus, a 1 kiloton nuclear weapon is one which produces the same amount of energy in an explosion as does 1 kiloton (1,000 tons) of TNT. Similarly, a 1 megaton weapon would have the energy equivalent of 1 million tons of TNT. One megaton is equivalent to 4.18 x 1015 joules.

**How big is a kiloton explosion?**

… atomic bombs is measured in kilotons, each unit of which equals the explosive force of 1,000 tons of TNT. The explosive power of hydrogen bombs, by contrast, is frequently expressed in megatons, each unit of which equals the explosive force of 1,000,000 tons of TNT.

**How is explosive yield measured?**

The explosive yield of atomic bombs is measured in kilotons (one kiloton equals the explosive force of 1,000 tons of TNT) while the explosive power of thermonuclear bombs is frequently expressed in megatons (one megaton equals the explosive force of 1,000,000 tons of TNT).

## How is TNT measured?

atomic bombs is measured in kilotons, each unit of which equals the explosive force of 1,000 tons of TNT. The explosive power of hydrogen bombs, by contrast, is frequently expressed in megatons, each unit of which equals the explosive force of 1,000,000 tons of TNT.

### How big is a 4 megaton explosion?

What if a bomb with a yield of 4 megatons – a convenient term for a blast equivalent of 4 millions of TNT, or about 200 times larger than the Hiroshima bomb – had detonated at Goldsboro?

#### Why is explosion measured in TNT?

The energy released in an explosion of 1 gram of TNT is approximately 4000 Joules. It is common to measure the power of an explosion by asking how much TNT would be needed to produce an explosion as powerful. This is called a TNT equivalent of an explosion.
