Liquidity Index formula |

| \( l_l \;=\; w - w_p \;/\; l_p \) | ||
| Symbol | English | Metric |
| \( l_l \) = Liquidity Index | \(dimensionless\) | \(dimensionless\) |
| \( w \) = Natural Water Content | \(dimensionless\) | \(dimensionless\) |
| \( w_p \) = Lower Plastic Limit (Plastic Limit) | \(dimensionless\) | \(dimensionless\) |
| \( l_p \) = Plasticity Index | \(dimensionless\) | \(dimensionless\) |
Liquidity index, abbreciated as \(l_l\), is the range of water content to the liquid limits.
