Cremation is a method of final disposition of a deceased person’s body through burning. Cremation reduces the body to its basic elements through exposure to intense heat and flame. The remaining bone fragments are then processed into ashes.
When a 200 lb person is cremated, their body mass is dramatically reduced. This raises the question: how much does a 200 lb person actually weigh after cremation?
Cremation Process Overview
During cremation, a deceased person’s body is placed into a cremation chamber or retort and subjected to extremely high temperatures, between 1400-1800°F. The intense heat vaporizes the body’s fluids and soft tissues and breaks down the skeletal structure.
The cremation process usually takes 2-3 hours for an average adult body to be reduced to bone fragments. These fragments are then raked out of the cremation chamber and any metal surgical implants are removed. The remaining bone pieces are pulverized into a powdery consistency using a machine called a cremulator.
This processing of bone fragments produces the cremated remains, often referred to as ashes. However, what remains after cremation are technically not ashes in the traditional sense, as complete combustion does not occur during cremation.
What Determines the Amount of Cremated Remains?
The amount of cremated remains left after cremation depends on a few key factors:
- Body weight – Heavier individuals will have more bone mass and therefore produce more cremated remains.
- Bone density – The density and volume of a person’s bones also impacts cremated remains weight.
- Age – Younger people have higher bone density and would yield slightly more cremated remains than older individuals.
- Removal of pacemakers or implants – Any surgical metal devices are removed prior to processing, reducing the weight.
The water content in the body and combustible nature of the casket or container used can also influence final cremated remains weight.
How Much Do Cremated Remains Weigh?
On average, cremated remains weigh between 4 to 8 pounds for an adult body. However, the precise weight varies case-by-case.
Generally, cremated remains weigh about 5% of the person’s total body weight prior to cremation. So for a 200 lb individual, their cremated remains would weigh approximately 10 pounds.
Here is a quick reference:
Average Weight of Cremated Remains
| Body Weight Before Cremation | Weight of Cremated Remains |
|---|---|
| 100 lbs | 4 to 5 lbs |
| 150 lbs | 7 to 8 lbs |
| 200 lbs | 10 lbs |
| 250 lbs | 12 to 13 lbs |
As shown, a 200 lb person would expect to yield about 10 pounds of cremated remains. However, the exact weight can’t be known until after cremation. Slight variations are normal.
Why Cremated Remains Weigh So Much Less
Cremation reduces a body down to just the remaining bone matter. Everything else is eliminated through the process.
Here’s a breakdown of what accounts for the massive reduction in weight after cremation:
- Water – The human body is over 60% water. Water is evaporated during cremation.
- Soft tissues – Muscle, fat, organs etc. are all incinerated, leaving no tissue mass.
- Non-bone matter – Ligaments, cartilage and other non-skeletal mass is burnt away.
- Pulverization – Bone fragments are ground down into small particles, reducing their weight.
By eliminating everything but bone matter, cremation can reduce a 200 lb person’s weight by over 90%. That is why only around 5-10 lbs of cremated remains is left at the end of the process.
What About Obese Individuals?
Obese individuals with extra body fat and weight will produce slightly more cremated remains than persons of average weight.
For obese individuals over 300 lbs, their cremated remains may weigh 10% or more of their body weight vs. just 5% for a person of normal weight.
Here is an estimate for obese individuals:
Cremated Remains Weight – Obese Individuals
| Body Weight Before Cremation | Weight of Cremated Remains |
|---|---|
| 300 lbs | 15 to 20 lbs |
| 350 lbs | 20 to 25 lbs |
| 400 lbs | 25 to 30 lbs |
| 450 lbs | 30 to 35 lbs |
The extra fatty tissue and higher bone density from obesity may raise the cremated remains weight. Even so, the weight reduction remains around 90-95% for larger individuals.
Volume of Cremated Remains
In addition to weighing the cremated remains, some family members are curious about the volume.
On average, the volume of cremated remains takes up 120-200 cubic inches of space. That’s equivalent to about 1 cubic foot. For perspective, cremated remains could fill an urn, small box, or plastic bag approximately the size of a football.
However, like the weight, the exact volume can vary person to person based on bone density, body size, and how finely pulverized the remains are processed.
Storing or Scattering Cremated Remains
Once the cremated remains are processed, they are placed in a rigid container and returned to the deceased’s family. The cremated remains belong to the family, and they can choose how to store or scatter them according to their wishes.
Some options for cremated remains include:
- Keeping the remains in an urn or decorative box for display
- Burying the remains in a grave or family plot
- Scattering remains in a meaningful location
- Incorporating remains into jewelry or other memorial keepsakes
- Interning remains in a columbarium niche
Having the cremated remains enables families to honor their loved one through memorialization or symbolic rituals for laying them to rest.
Legalities of Handling Cremated Remains
It is important for families to handle cremated remains in accordance with applicable state and local laws. Some key guidelines include:
- Proper packaging and transport of remains
- Obtaining any necessary permits for scattering
- Following rules for scattering remains on public land
- Not abandoning remains or scattering in unauthorized areas
Failing to follow regulations for handling cremated remains could result in legal penalties. Families should research their options to ensure proper handling.
Conclusion
The cremation process significantly reduces a body’s original weight and volume. For a 200 lb individual, their remains would weigh around 5-10 lbs – just a fraction of their initial body weight.
The majority of the body’s mass is reduced through incineration of fluids, soft tissues, and non-bone matter. Only the hardened and pulverized bone fragments remain.
Though cremated remains are compact, they still enable families to honor their deceased loved one through memorialization, interment, or scattering. By understanding the cremation process, families can better appreciate the significance of cremated remains in their grief journey and healing.
