What is SI unit of time?
The second, symbol s, is the SI unit of time.
It is defined by taking the fixed numerical value of the caesium frequency Cs.
, the unperturbed ground-state hyperfine transition frequency of the caesium-133 atom, to be 9 192 631 770 when expressed in the unit Hz, which is equal to s–1..
What is a healthy weight?
If your BMI is less than 18.5, it falls within the underweight range. If your BMI is 18.5 to 24.9, it falls within the normal or Healthy Weight range. If your BMI is 25.0 to 29.9, it falls within the overweight range. If your BMI is 30.0 or higher, it falls within the obese range.
What are the 7 units of measurement?
The SI system, also called the metric system, is used around the world. There are seven basic units in the SI system: the meter (m), the kilogram (kg), the second (s), the kelvin (K), the ampere (A), the mole (mol), and the candela (cd).
What is formula for mass?
One can consider the mass of an object as a measure of how much physical “stuff” makes up that object. mass=density×volume (m=ρV). Density is a measure of mass per unit of volume, so the mass of an object can be determined by multiplying density by volume.
What is heavier than a ton?
Weight is measured in the U.S. customary system using three units: ounces, pounds, and tons. An ounce is the smallest unit for measuring weight, a pound is a larger unit, and a ton is the largest unit. Whales are some of the largest animals in the world.
What is the smallest unit?
Zeptosecond – the smallest time unit ever measuredGetty Images. See you in a zeptosecond! … Getty Images. A zeptosecond is a trillionth of a billionth of a second. … Sven Grundmann/Goethe University. The scientists used a particle accelerator machine and a super-powerful laser called the PETRA III.
What are 3 common units of volume?
Three common units of volume are:cubic centimeters.liters.gallons.
What are the common units of weight?
Weight is a quantity of heaviness. For example, you are measuring the weight of your body when you step on to a scale. In the customary system of measurement, the most common units of weight are the ounce (oz) and pound (lb).
What is the weight of human brain?
The average brain weight of the adult male was 1336 gr; for the adult female 1198 gr. With increasing age, brain weight decreases by 2.7 gr in males, and by 2.2 gr in females per year. Per centimeter body height brain weight increases independent of sex by an average of about 3.7 gr.

Is LB a weight or mass?
The international standard symbol for the pound as a unit of mass is lb. In the “engineering” systems (middle column), the weight of the mass unit (pound-mass) on Earth’s surface is approximately equal to the force unit (pound-force). This is convenient because one pound mass exerts one pound force due to gravity.
What is standard unit?
Standard units are the units we usually use to measure the weight, length or capacity of objects.
What weight is smaller than a gram?
To measure weights smaller than 1 gram, we can use milligrams (mg) and micrograms (µg). 1000 mg = 1 g, 1000 µg = 1 mg, 1 000 000 µg = 1 g.
What is my ideal weight in kg?
Based on the BMI range, it is possible to find out a healthy weight for any given height….B. J. Devine Formula (1974)Male:50.0 kg + 2.3 kg per inch over 5 feetFemale:45.5 kg + 2.3 kg per inch over 5 feet
What is the unit of human weight?
kilogramsHuman body weight refers to a person’s mass or weight. Body weight is measured in kilograms, a measure of mass, throughout the world, although in some countries such as the United States it is measured in pounds, or as in the United Kingdom, stones and pounds.
How can I calculate weight?
SummaryWeight is a measure of the force of gravity pulling down on an object. It depends on the object’s mass and the acceleration due to gravity, which is 9.8 m/s2 on Earth.The formula for calculating weight is F = m × 9.8 m/s2, where F is the object’s weight in Newtons (N) and m is the object’s mass in kilograms.
What is the smallest unit of weight?
