Is there an option in Intl.NumberFormat() to automatically convert to bigger units?

I'd like Intl.NumberFormat() to automatically convert between units from smaller to bigger ones based on common rules. I.e. a given number should be converted to between centimeters, meters, and kilometers in the output depending on how big the number is.

Code examples:

const bytes = 1000000;
const transferSpeed = new Intl.NumberFormat('en-US',
  {style: 'unit', unit: 'byte-per-second', unitDisplay: 'narrow'}).format(bytes);
console.log(transferSpeed);

const days = 365;
const timespan = new Intl.NumberFormat('en-US',
  {style: 'unit', unit: 'day', unitDisplay: 'long'}).format(days);
console.log(timespan);

The output of these two calls is:

1,000,000B/s
365 days

In that case I'd expect this, though:

1MB/s
1 year

And one might want to define the threshold for when to convert to the next bigger unit. So it could be that the conversion should happen once the exact value is reached but also earlier, let's say at 90% of the next bigger unit. Given the examples above, the output would then be this:

0.9MB/s
0.9 years

Are there configuration options for the API to do that?
