Bathroom scales are fickle devices. They can give you a different weight from day to day, or even moment to moment. … In general, digital bathroom scales are more accurate than mechanical ones.
Moreover, Are kilograms more accurate?
Originally Answered: Are pounds more accurate than kilograms on a weight scale? They can’t be. The pound is defined by the kilogram, 1 lb = 0.453 592 37 kg. We have no primary independent pound standard, just a declared definition via the SI.
In respect to this, Are lbs more accurate?

Which is better kilograms or grams?
Measuring Mass in Kilograms and Grams We write kg for kilogram and g for gram. 1 kilogram is heavier than 1 gram.
Furthermore, Why is weighing yourself in Kg incorrect?
Weight is the amount of force on an object due to gravity. … To review, a person or an object has a mass that can be measured in kg. A person or an object that is on any celestial body with gravity has a weight that can be measured in N. It is completely incorrect to say that a person or an object has a weight in kg.
Why do we use kg instead of G?
Kilogram becoming a base unit: the role of units for electromagnetism. As it happens, it is mostly because of units for electromagnetism that the kilogram rather than the gram was eventually adopted as the base unit of mass in the SI. … the sizes of the base units of length and mass are convenient for practical use.
Is it better to weigh yourself in kg or stone?
It’s very simple to weigh yourself in kilograms, whether you have mechanical or electronic scales. If you are being weighed by a health professional, you are already being weighed in kilograms, but they often convert it to stones and give it back to you in stones and pounds, which leaves room for error in conversion.
Why is it not scientifically correct to say your weight is 65 kg?
Weight is the amount of force on an object due to gravity. Therefore, weight is the mass (the amount of stuff) multiplied by the acceleration due to gravity. … It is completely incorrect to say that a person or an object has a weight in kg.
Is kg better than g?
A kilogram is 1,000 times larger than one gram (so 1 kilogram = 1,000 grams).
Which is more accurate pounds or kilograms?
One kilogram is approximately equal to 2.2 pounds. So a kilo is 2.2 times heavier than a pound. … “Kilogram” is a more widely used unit of measure for mass than the pound.
Why do we weigh ourselves in kilograms?
Scales show Kilograms because that is what people understand best … … So the scales show an estimate of your mass based on the force your body exerts on it. And to find out how much force your body is exerting on the scales, multiply by 9.8 (to convert kg into Newtons).
Where is the best place to weigh yourself at home?
The Right Way to Weigh In Place your scale on a hard, even surface—no carpeting. A wobbly or tilted scale can result in an inaccurate reading. Stand still, with your weight distributed evenly on both feet. If you’re using a body-fat scale, you should be barefoot.
Why is kg used for mass?
Since there is no practical easy way to measure mass, in everyday life we use the kilogram as a unit of weight assuming that the gravitational field is fairly constant around earth. However scales have to be calibrated locally to compensate the slight gravitational field variation in different places.
Which is more g or kg?
Using this table as a reference, you can see the following: • A kilogram is 1,000 times larger than one gram (so 1 kilogram = 1,000 grams).

What is the best time to weigh yourself?
For the most accurate weight, weigh yourself first thing in the morning. “[Weighing yourself in the morning is most effective] because you’ve had adequate time to digest and process food (your ‘overnight fast’).
Do you use kg or g in physics?
You do not specifically need to use either g or kg in any specific problem; you just have to ensure that your units are consistent throughout the problem. If all of the quantities in a given problem are in kilograms, it’s probably easier to use kilograms.
How do I get an accurate weight?
– Weigh yourself at the same time every day (morning is best, after using the restroom).
– Use a quality weighing device that’s set up properly.
– Only use one scale.
– Weigh yourself naked or wear the same thing for every weight measurement.
Why is mass in kg?
Because of this, the scientific community adopted the SI system in 1960, with the kilogram as base unit. In summary: the kilogram became the base unit because it is coherent with the joule, which is derived from the practical units volt and ampere.
