Converts a value from the current G-code unit (G20 for inches, G21 for millimeters) to millimeters.

unit_to_mm(value)

• The equivalent value in millimeters.
• If G21 (millimeters) is active, the value remains unchanged.
• If G20 (inches) is active, the value is converted from inches to millimeters.

Convert 1 inch to millimeters (assuming G20 is active)

unit_to_mm(1);  // returns 25.4

Convert 100 mm to millimeters (assuming G21 is active)

unit_to_mm(100);  // returns 100
