Measurement resolution ratio calculator

Calculate resolution to tolerance span and nominal increments across tolerance with your own figures.

Your numbers

Use the units shown. Results update as you change valid inputs.

Use resolution to tolerance span and nominal increments across tolerance to compare changes to your inputs. The method and limits below explain the scope.

Examples

Examples

Try the starting example

Resolution increment (measurement units)
0.01
Lower tolerance limit (measurement units)
9.5
Upper tolerance limit (measurement units)
10.5
Resolution to tolerance span (%)
1
Nominal increments across tolerance
100

Try another scenario

Resolution increment (measurement units)
0.02
Lower tolerance limit (measurement units)
9.5
Upper tolerance limit (measurement units)
10.5
Resolution to tolerance span (%)
2
Nominal increments across tolerance
50
Calculation method

Calculation method

Resolution to tolerance span (%)

100*resolution/(upper-lower).

Nominal increments across tolerance

(upper-lower)/resolution.

Symbols and units
a
Resolution increment (measurement units)
b
Lower tolerance limit (measurement units)
c
Upper tolerance limit (measurement units)

Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.

Assumptions & limits

Assumptions & limits

  • Descriptive ratio only. No universal pass criterion, uncertainty assessment or measurement capability claim. Supported limits: resolution>0; upper>lower.
