How to convert millisieverts to microsieverts

To convert millisieverts to microsieverts, multiply the value by the factor: 1 mSv = 1,000 µSv. In reverse: 1 µSv = 0.001 mSv. Enter a number above for an instant result.

Microsievert and millisievert are submultiples of the sievert. Microsieverts suit background radiation and consumer dosimeters; millisieverts suit medical procedures and annual limits. 1 mSv = 1000 µSv.

Use it to convert values from source certificates, reports and regulations. Need other units? The full dose converter has sievert, rem, gray, rad and roentgen.

Examples: 1 mSv = 1,000 µSv; 10 mSv = 10,000 µSv; 100 mSv = 100,000 µSv; 1,000 mSv = 1,000,000 µSv. Reverse: 1 µSv = 0.001 mSv.
