What size urn do I need to order?
As an industry rule of thumb, for every 1lb the deceased weighed at the time of death the urn should have at least 1 cubic inch in volume. So 1lb = 1 cubic inch
Translated into imperial measures, the below table should help you decide the size of the urn you need. Typically, an urn for human ashes comes in 2.5-3.5 litres to hold the full remains and this will be suitable for 99% of cases.
Ashes Urn Size Guide
Volume of Human Ashes
|POUNDS (Deceased Weight)||URN VOLUME (Cubic Inches)||URN VOLUME (Litres)||STONE(Deceased Weight)||KG (Deceased Weight)||WEIGHT OF ASHES (Approx)|
|1lb||1 cubic inch||17 millilitres||0.072||0.45kg||13 grams|
|62lb||62 cubic inches||1 Litre||4.5 Stone||28.5kg||0.85 kg|
|168lb||168 cubic inches||2.8 Litres||12 Stone||76.2kg||2.17 kg|
Important Note: Height is also a contributing factor towards the total size you will need. Taller people will inherently have longer bones so there will be more ash. Fat is burnt away during the cremation process, so will have less of a bearing on the final amount of ashes. This should be taken into account when calculating the urn you will need.
How heavy are cremated remains? How much do ashes weigh?
Ashes will weigh approximately 3.5% of the body’s weight.
Again, there are a number of factors, but the industry rule of thumb is that the ashes will weigh approximately 3.5% of the body’s weight.
The calculation looks like this:
Weight X 0.035 = Weight of Ashes
EG 12 stone is 168lbs x 0.035 = 5.88lbs in ashes
