Convert pound-force square second/foot to ton (assay) (US) [AT (US)] Online | Free weight-and-mass Converter

It looks like you mentioned "pound-force square second per foot". This is a compound unit that can be broken down into:

pound-force (lbf): a unit of force
square second (s²): time squared
per foot (ft⁻¹): per unit length

What does this unit represent?

It could be a unit for something like mass or inertia-related quantities in imperial units, depending on context. For example, it might show up in equations involving force, time, and length — possibly in mechanics or engineering.

To understand or convert it:

Pound-force (lbf) is a force unit, where:

1\, \text{lbf} = 4.44822\, \text{N}

Second squared (s²) is just time squared.
Foot (ft) is length:

1\, \text{ft} = 0.3048\, \text{m}

Example usage

If you want to convert pound-force square second per foot $(\text{lbf} \cdot \text{s}^2/\text{ft})$ into SI units:

\text{lbf} \cdot \text{s}^2/\text{ft} \rightarrow \text{Newton} \cdot \text{s}^2/\text{meter}

Since

1\, \text{lbf} = 4.44822\, \text{N}, \quad 1\, \text{ft} = 0.3048\, \text{m}

1\, \frac{\text{lbf} \cdot \text{s}^2}{\text{ft}} = \frac{4.44822\, \text{N} \cdot \text{s}^2}{0.3048\, \text{m}} \approx 14.6\, \frac{\text{N} \cdot \text{s}^2}{\text{m}}

Could you tell me more about where or how you want to use this unit? That would help me give a more specific explanation or conversion!

Ton (Assay) (US) [AT (US)]

The assay ton (AT) is a specialized unit of weight used in the mining and precious metals industries in the United States. It is primarily used to measure ore quantities for assaying, which is the process of analyzing the metal content of ore samples.

One assay ton equals 29.1667 pounds (about 13.23 kilograms), which is different from the standard short ton (2,000 pounds). This smaller ton unit allows for more precise measurements in evaluating the value of ore deposits.

The assay ton helps miners and metallurgists accurately calculate the concentration of valuable metals like gold and silver in ores.
