Is anything smaller than Planck length?
The question of whether space and time are discrete or continuous, and whether there’s a smallest possible length scale, is still unanswered. However, we do know that below the Planck distance scale, we cannot predict anything with any accuracy at all.
How long is 1 Planck time?
A Planck time unit is the time required for light to travel a distance of 1 Planck length in a vacuum, which is a time interval of approximately 5.39 × 10−44 s.
What is smaller than a Picometer?
There are measurements smaller than 1 Angstrom – 1 picometer is 100 times smaller, and 1 femtometer (also known as a fermi) is 100,000 times smaller, and is about the size of an atomic nucleus.
Is PG smaller than Ng?
1 Nanogram is exactly 0.000000000001 kilograms (SI unit). As per the prefix nano it is a billionth of a gram; a gram is a thousandth of a kilogram. 1 ng = 0.000000000001 kg. … 1 pg = 0.000000000000001 kg.
Which is heavier kg or LB?
Both pound and kilogram are units of measurement of weight or mass. A pound is an imperial unit of mass or weight. … A kilogram (kg) is stated to be 2.2 times heavier than a pound (represented as lbs). Thus, one kilo of mass is equal to 2.26lbs.
What’s the smallest weight?
U.S. Customary Units
An ounce is the smallest unit of weight. A strawberry has a weight of about 1 ounce.
Is CM a SI unit?
The base unit of length in the SI system is the meter(m). The meter, approximately 10% longer than a yard, is equivalent to 39.37 inches, or 1.094 yards.
…
| Unit of length | Relationship to base unit |

| millimeter (mm) | 1000 mm = 1 m |
| micrometer (µm) | 106 µm = 1 m |
| nanometer (nm) | 109 nm = 1 m |
What is SI unit of length Class 6?
The SI unit of length is metre (m).
What is SI unit of weight?
The SI unit of mass is the kilogram (kg). In science and technology, the weight of a body in a particular reference frame is defined as the force that gives the body an acceleration equal to the local acceleration of free fall in that reference frame.
