Got no scale to measure your weight? Then don’t despair as I’ll teach you how to weigh yourself without a scale. You might think that there is no way to do it, but mathematics and science will tell you otherwise.
When my weighing scale got broken, I was devastated because I can’t keep track on my weight loss progress. Although you can buy a weighing scale conveniently, I tried to search for alternative ways. If you’re interested to know, keep on reading.
What You’ll Need
Calculator is your friend if you’ll measure your weight without the scale. You need to do basic mathematics to get your estimated weight. Any type of calculator will do- scientific, the basic model, or even the one found on your phone.
For Method 1, the calculator will be needed to calculate the volume of water displaced. For Method 2, the calculator will be used to multiply the number of 1-gallon cans by the conversion factor, 8.33 pounds, to get your weight.
For Method 1: Water Displacement
For the water displacement method, the container you’ll need should be large enough to submerge yourself completely. If you have a bathtub, the better, but if you don’t, then find an empty water barrel that will fit you properly.
The pen marker is essential in determining the water displaced. You’ll need to mark the container to be guided on how much water to fill. While you’re submerged in the water, you also need to mark the level of water again.
With the two markers, you can measure the vertical distance to get the volume of water displaced. Alternatively, you can use a grease pencil if you can’t find a pen marker at home.
Another item that you need to have for this water displacement method is a tape measure. The tape measure will be needed when you’ll measure the length and width of your container. Use any tape measure that you have available.
To measure the vertical distance between the two markers, a ruler might be more convenient. If you have no ruler available, you can use the tape measure the vertical distance of two water levels.
Of course, the water displacement method won’t be complete without water. You might need to use a lot of water since you’ll be submerging yourself from head to toe. To avoid any skin irritations, use clean water always.
For Method 2: Lever And Fulcrum
Cans Of Paint
For this lever and fulcrum method, several cans of paint will be needed to balance yourself in the see-saw. The best size of paint cans is one gallon. However, you might need to prepare a couple of smaller sizes to get an accurate weight reading. Alternatively, you can use one-gallon water containers.
The see-saw will be used as a place where you and the cans balance each other. If you have a see-saw built outside your home, then you’re lucky. However, if you don’t, then it might be best to build your own. I know, it sounds inconvenient, but you can always get a long lumber to make a lever and some wood for the fulcrum.
Method 3: Body Fat Measurement
Skin Fold Caliper
To get the accurate measurements of your body fat composition around your triceps, thighs, and stomach area. You can buy a skinfold caliper for less than $10.
Soft Tape Measure
The soft tape measure will be used to get the circumference of your waist. Make sure that the tape measure you used still have visible numerical markings so the circumference will be easy to read.
Pen And Notebook
To keep track on your progress, you need to write the measurements on a notebook. This will help tell you whether you’re losing weight or not.
Method 1: Water Displacement
In the water displacement method, we’ll be using the Archimedes Principle which holds the formula: density = mass/ volume.
For water, the density is 1 gram per cubic centimeter, so whatever the volume of water displaced is, it will be equivalent to your weight in grams.1
Mark And Fill The Container
To begin, use the tape measure to get the surface area (length * width) of your container in centimeters. Next, mark a height that’s a bit lower than the top of your container to indicate the first level of water. Now, fill the container with water up to the height that you marked.2
Submerge Yourself Into The Container And Mark
Submerge yourself into the container that’s filled with water. To mark the rise of water level, asked someone to do it for you because it might be hard while you’re under water.3
Calculate The Volume Displaced
After that person marked the change of water level, get out of the water before you lose your breath now, get ready to measure the volume displaced by your body. Use a ruler to get the vertical distance in centimeters between the two markers.
To get the volume displaced, multiply the surface area of your container with the vertical distance between two markers. So if your surface area is 3000 centimeters and the vertical distance displaced is 20 centimeters, then the volume displaced is 60,000 cubic centimeters. Since your weight is equal to the volume displaced, your weight will be 60,000 grams or 60 kilograms.
Method 2: Lever And Fulcrum
In this lever and fulcrum method, we’ll be using the number of cans to get your estimated weight. Here are the complete steps.1
Place Cans At The Other End Of The See-Saw
Position yourself at the end of the see-saw. While sitting, ask someone to place the 1-gallon cans of paint or 1-gallon water on the other side. You’ll possibly notice that you get lifted off the ground when more cans are placed on the other end.
If your see-saw gets a perfect balance, stop adding more load. If not, consider adding a smaller-sized load, like half gallons or quarters until you reach the perfect balance.2
Calculate Your Estimated Weight
To get your weight in pounds, count the number of cans used and multiply it by 8.33, assuming that you use all 1-gallon sized cans. For example, you used 11 cans, your weight will be 11 * 8.33 pounds = 91.63 pounds.
However, if you have mixed some half-gallons, count them separately. For example, you have used 10 one gallons and two half gallons, your weight will be: 91.63 + [2 * 1/2 * 8.33] = 99.96 pounds.
Method 3: Body Fat Measurement
This method won’t tell you of your weight per se, but it can help you keep track of how much weight you lose. Instead of focusing on your weight, you should focus on how many numbers you lose monthly. Here are the complete instructions.1
Measure Body Fat
Monitor your body fat by using the skin fold caliper around the triceps, suprailiac, and thigh. To use, gently pinch a skin around the body part that you want to measure and clip with the caliper, as shown in this video.
With your pen, record the results on your notebook. Since doing this daily or weekly won’t give visible results, do this body fat measurement monthly. Your target here is to see the number reduce each month.2
Measure Waist Circumference
The size of your waist will also determine if you have an excessive amount of fat, known as visceral fat. A waist larger than 35 inches on a woman or 40 inches on a man means a great surplus of visceral fat.
To measure your waist, use the soft tape measure and loop around your waist. Hold it firm and pressed into your skin. Make sure that your abdomen is relaxed when doing this. Like the caliper measurement, record results to track progress. If your waist circumference is getting lower, then it indicates weight loss.
Tips From The Experts
how to weigh yourself without a scale
1.Feel And See Your Body Change
Dr. Dan DiBacco suggests using your senses when measuring weight. You can tell that you’re losing or gaining weight based on your clothes. If they don’t fit, then it’s more likely that you have gained some weight.
Your reflection in the mirror will also tell you how much you weigh. If you’re getting bigger lately, then you should take this signal to watch your diet.
2.Take A Regular Activity Evaluation Test
Nutrition coordinator Kelly Hogan recommends taking a flight of stairs weekly. If you’re losing breath when you reach the top of the stairs, then it means your body is getting heavy. If not, then you’re doing right with your diet.
