Quick Answer
Calculate NIOSH Lifting Index (LI) Calculator
Calculator
Result Interpretation
NIOSH Lifting Index (LI) Calculator computes Lifting Index in dimensionless using the defined engineering formula and the input values provided. Lifting Index is expressed in dimensionless. No universal acceptance threshold is defined by this calculator.
Worked Example
Verified calculation
Given:
- Actual Load Weight = 12
- Recommended Weight Limit = 24
Expected Result:
- Lifting Index = 0.5
Engineering Interpretation:
Under the given input conditions, the calculated result is: Lifting Index = 0.5 dimensionless.
The actual numerical result is computed by the Runtime engine using the persisted tool definition. The values shown here come from automatically validated test cases.

Frequently Asked Questions
What does this calculator calculate?
The NIOSH Lifting Index (LI) Calculator estimates Lifting Index based on the input parameters you provide
Why is actual load weight important in this calculation?
actual load weight is directly proportional to lifting index. When you enter actual load weight in kg, the calculator uses it in the engineering formula to compute the output
How should I interpret the result lifting index?
The calculator outputs lifting index in dimensionless. The result is computed directly from the input values using the defined engineering formula
What units should I use for the inputs?
Enter each value in the units shown next to the input field: Actual Load Weight (kg), Recommended Weight Limit (kg). Make sure all inputs use the specified units for consistent results
What assumptions does this calculator use?
This calculator uses automatically validated engineering formulas. Results are approximate and should be validated against site-specific conditions, applicable codes, and professional engineering judgment
