Use String#split, Array#map and Array#join methods.

var str = "c:0.1|d:0.2";

console.log(
  str
  // split string by delimiter `|`
  .split('|')
  // iterate and generate result string
  .map(function(v) {
    // split string based on `:`
    var s = v.split(':')
      // generate the string
    return s[0] + ':' + (Number(s[1]) * 100) + "%"
  })
  // join them back to the format
  .join()
)

You can also use String#replace method with capturing group regex and a callback function.

var str = "c:0.1|d:0.2";

console.log(
  str.replace(/\b([a-z]:)(0\.\d{1,2})(\|?)/gi, function(m, m1, m2, m3) {
    return m1 +
      (Number(m2) * 100) + // calculate the percentage value
      (m3 ? "%," : "%") // based on the captured value put `,`
  })
)

It's not angular issue, you can use simple logic, use substring take value after the : and multiply by 100 to get the value as 10 or respective.
