Because the nature of this package, some raw conversion does not resulting in same value, for example:

void main(){
  print([Feet(1), Inches(12)].toInches); // 24.00000000006096
  print([Feet(1), Inches(12)].toInches.withPrecision()); // 24
  print([Feet(1), Inches(12)].toFeet); // 1.9999999999949203
  print([Feet(1), Inches(12)].toFeet.withPrecision()); // 2
  print(Inches(12).toFeet); // 0.9999999999949201
  print(Inches(12).toFeet.withPrecision()); // 1
  print(Inches(12).toInches); // 12
  print(Inches(12).toInches.withPrecision()); // 12
  print(Feet(1).toFeet); // 1
  print(Feet(1).toFeet.withPrecision()); // 1
  print(Feet(1).toInches); // 12.000000000060961
  print(Feet(1).toInches.withPrecision()); // 12
}

Use withPrecision() for more precision
