Concrete Volume Calculator - Imperial
This Concrete Volume Calculator (Imperial) is designed for continuous use: pick an item, enter its dimensions, click Calculate, and watch it roll into your project total-no need to clear between entries. Each calculation adds a new line to your history and instantly updates the Running Totals in ft³, yd³ and m³. Keep adding footings, walls, columns, pads, pillars or slabs until your entire job is logged. Want to start over? Just hit Clear History to reset both the list and all totals to zero.
Calculator Options:
- Footings - Length (ft/in), Width (ft/in), Depth (in)
- Foundation Walls - Length (ft/in), Height (ft/in), Thickness (in)
- Round Columns - Diameter (in), Height (ft/in)
- Pads - Length (ft/in), Width (ft/in), Depth (in)
- Rectangle Pillars - Length (in), Width (in), Height (ft/in)
- Slabs - Length (ft/in), Width (ft/in), Thickness (in)
- Rectangular Pad & Column - Quantity (#), Column Length (in), Column Width (in), Column Height (ft/in), Pad Length (ft/in), Pad Width (ft/in), Pad Depth (in)
- Circular Column & Square Pad - Quantity (#), Column Diameter (in), Column Height (ft/in), Square Pad Size (ft/in), Pad Depth (in)
- Curb & Gutter - Length (ft), Curb Depth (in), Curb Height (in), Gutter Width (in), Flag Thickness (in)

Concrete Volume Formulas (Imperial)
Footings
\[ L = L_{ft} + \frac{L_{in}}{12}, \qquad W = W_{ft} + \frac{W_{in}}{12}, \qquad D = \frac{D_{in}}{12} \]
\[ V_{\text{footing}} = L\,W\,D \]
Foundation Walls
\[ L = L_{ft} + \frac{L_{in}}{12}, \quad H = H_{ft} + \frac{H_{in}}{12}, \quad T = \frac{T_{in}}{12} \]
\[ V_{\text{foundation}} = L\,H\,T \]
Round Columns
\[ D = \frac{D_{in}}{12}, \qquad H = H_{ft} + \frac{H_{in}}{12} \]
\[ V_{\text{column}} = \pi\left(\frac{D}{2}\right)^{2}H \]
Pads
\[ L = L_{ft} + \frac{L_{in}}{12}, \quad W = W_{ft} + \frac{W_{in}}{12}, \quad D = \frac{D_{in}}{12} \]
\[ V_{\text{pad}} = L\,W\,D \]
Rectangle Pillars
\[ L = \frac{L_{in}}{12}, \quad W = \frac{W_{in}}{12}, \quad H = H_{ft} + \frac{H_{in}}{12} \]
\[ V_{\text{pillar}} = L\,W\,H \]
Slabs
\[ L = L_{ft} + \frac{L_{in}}{12}, \quad W = W_{ft} + \frac{W_{in}}{12}, \quad T = \frac{T_{in}}{12} \]
\[ V_{\text{slab}} = L\,W\,T \]
Rectangular Pad & Column (n units)
\[ V_{\text{col}} = L_{c}\,W_{c}\,H_{c}, \qquad V_{\text{pad}} = L_{p}\,W_{p}\,D_{p} \]
\[ V_{\text{total}} = n\,(V_{\text{col}} + V_{\text{pad}}) \]
\[ L_{c} = \frac{L_{c,in}}{12},\; W_{c} = \frac{W_{c,in}}{12},\; H_{c} = H_{c,ft} + \frac{H_{c,in}}{12} \]
\[ L_{p} = L_{p,ft} + \frac{L_{p,in}}{12},\; W_{p} = W_{p,ft} + \frac{W_{p,in}}{12},\; D_{p} = \frac{D_{p,in}}{12} \]
Circular Column & Square Pad (n units)
\[ D = \frac{D_{in}}{12}, \quad H = H_{ft} + \frac{H_{in}}{12}, \quad S = S_{ft} + \frac{S_{in}}{12}, \quad D_{p} = \frac{D_{p,in}}{12} \]
\[ V_{\text{col}} = \pi\left(\frac{D}{2}\right)^{2}H, \qquad V_{\text{pad}} = S^{2}D_{p} \]
\[ V_{\text{total}} = n\,(V_{\text{col}} + V_{\text{pad}}) \]
Curb & Gutter
\[ d = \frac{d_{in}}{12},\; h = \frac{h_{in}}{12},\; w = \frac{w_{in}}{12},\; t = \frac{t_{in}}{12} \]
\[ A_{\text{curb}} = d\,h ,\qquad A_{\text{flag}} = (d+w)\,t \]
\[ V_{\text{curb\&gutter}} = (A_{\text{curb}} + A_{\text{flag}})\,L_{ft} \]
