Some wrench sets come in metric units and others come in standard units. A chart compares the measurements of a metric set of wrenches with the equivalent measurements in inches.Metric to Inches ConversionMetric wrench size in millimetersEquivalent size ininches 40.157250.196560.235870.275180.314490.3537If Caleb only has metric wrenches and needs a inch wrench, how could he use the chart to choose the best fit?

Caleb should use the 5 millimeter wrench because that would be closest to inches since they both have 5.
