Percent Tolerance Calculator
Find the allowed range for a nominal value with a ± percent tolerance, and check whether a measurement passes.
Allowed range
95 to 105
- ± amount
- 5
- Measured value
- Within tolerance (+3%)
Show the work
The ± amount
d = |nominal| × tolerance %
100 × 5% = 5
Nominal ± d
nominal − d to nominal + d
100 − 5 to 100 + 5 = 95 to 105
How it works
Range = nominal × (1 − tolerance ÷ 100) to nominal × (1 + tolerance ÷ 100)
Questions
- How does the percent tolerance calculator work?
- Range = nominal × (1 − tolerance ÷ 100) to nominal × (1 + tolerance ÷ 100).
- What do I need to enter?
- Nominal value, Tolerance (±), Measured. Optional fields can be left blank.
