Conversions between metric system units are easy because the system is based on powers of ten. For example, there are 100 centimeters in 1 meter, 1000 meters in 1 kilometer. Conversely, there are 1 ...

As far as “un-metric in spirit” goes, the metric system has added more prefixes on multiple occasions. We all had to memorize what femto and atto mean, and nobody had any problems with that.

The new prefixes ronna and quetta refer to the largest numbers, while ronto and quecto apply to the smallest. Ronna is a 1 followed by 27 zeroes, and quetta is a 1 followed by 30 zeroes.

Yotta (24 zeroes) was the largest prefix in the metric system before the new additions. Now, the Earth's mass can be said to be about 6 ronnagrams rather than 6,000 yottagrams.

IEEE 1541-2002 (adopted in 2005 and reaffirmed in 2008) defines that standard metric prefixes should not be used when referring to base 2 numbers, typical in computing. Metric uses base ten for ...

As you may have guessed, we also now have terms for 10-27 and 10-30: ronto and quecto.. While there are few things that can’t adequately be described in terms of the existing prefixes, it’s ...

The prefixes make it easier to express large amounts -- for example, always referring to a kilometre as 1,000 metres or a millimetre as one thousandth of a metre would quickly become cumbersome.

The Earth can now be said to weigh about 6 ronnagrams - or 6,000,000,000,000,000,000,000,000,000g ...
