Graphene is a type of carbon material that has gained widespread attention due to its unique properties, such as high strength, electrical conductivity, and thermal conductivity. However, it is not surprising to see that there are some people who argue that graphene might be lighter than steel.

Firstly, let’s consider the weight of each material. Graphene is about one-third as dense as water, making it one of the lightest materials known to date. This means that a single sheet of graphene could weigh less than a grain of sand. In contrast, steel is typically made from iron and carbon, which has a density of about 7.8 g/cm3.
One potential advantage of using graphene for construction is that it would reduce the overall weight of buildings and structures. With its lightweight nature, it could potentially save millions of dollars in building costs by reducing the amount of steel required to construct the same structure. Additionally, using graphene for construction could have environmental benefits as well, as it would be more sustainable and energy-efficient than traditional building materials.
Another factor to consider when comparing weight between graphene and steel is their strength-to-weight ratio. Graphene has been shown to have a tensile strength of up to 120 gigapascals (GPa), which is several times stronger than steel. This means that if we were able to use graphene as a structural material, it would be much stronger than any steel used today.

In conclusion, while it is true that graphene is lighter than steel in terms of weight, this does not necessarily mean that it would be better or more efficient. Both materials have their own unique strengths and weaknesses, and their optimal use will depend on a variety of factors, including cost, durability, and environmental impact. Ultimately, the choice between graphene and steel will likely come down to a balance between these various factors.
