The whole length of a metre scale is divided into500 equal parts then the smallest measurementthat can be measured by using the scale is _______.(a) 0.5 m (b) 0.005 m(c) 50 mm (d) 2 mm

number in inches, converts it to meters.Write a Java program that reads a number in inches, converts it to meters.The inch is a unit of length in the (British) imperial and United States customary systems of measurement now formally equal to ​1/36 yard but usually understood as ​1/12 of a foot.The meter is the base unit of length in some metric systems, including the International System of Units (SI). The SI unit symbol is m.Note: One inch is 0.0254 meter.Constraints:n/aExample:Input:Input a value for inch: 1000Output:1000.0 inch is 25.4 meters Explanation:-Public Test Cases:# INPUT EXPECTED OUTPUT1 100025.42 120030.4
