Easy calculator for area of steel rebars

Quickly find the area of steel rebars - based on "total number" or "spacing" - for "beams", "slabs" and "shear reinforcement".

It's very useful for civil engineers / structural engineers. Includes standard US, CA, and European rebar sizes (metric and non-metric units).

FEATURES
• Beam Reinforcement calculator
(area for a given number of rebars)

• Slab Reinforcement calculator
(area for rebars based on their spacing)

• Shear Reinforcement calculator
(area of stirrup legs for the specified spacing)

REBAR SIZES / UNITS
• US (#) rebar sizes with non-metric units (inch, foot)
• Canadian (M) rebar sizes with metric units (mm, m)
• European (Φ) standard rebar sizes with metric units (cm, m)
