...but you don't have to; any "angle" above 543us will be treated by write as a microseconds value

From Servo.h Library

void write(int value); // if value is < 200 its treated as an angle, otherwise as pulse width in microseconds 
void writeMicroseconds(int value); // Write pulse width in microseconds
