Summary
| Description | Denmark Photo of the Danish national Kilogram prototype, known as K48, is located at the Danish National Metrology Institute. The mass of K48 is documented as being 112 µg greater than that of the IPK—the International Prototype Kilogram—kept at the BIPM’s House of Breteuil in Sèvres on the outskirts of Paris. K48’s mass was compared to the IPK when it was made in the 1949 and was certified with its latest mass offset value during the 1989/1992 periodic verification. |

The original photograph upon which this image is based, Image:Kilogram.jpg on Commons, was received directly from the Danish National Metrology Institute by request. This is a slightly modified version of that original. It has been rotated ½°, colour and contrast-adjusted, dust cleaned up, and de-speckled. Due to less high-spatial frequency noise in the background, this version also has a file size only 74% that of the original. |
